USAGE OF TARGET TRACKING FUNCTION z There are the following limitations on use of the target acquisition and target tracking functions. Attention [I] Resolution between adjacent targets and swapping during automatic target tracking Depending on the particular distance and echo size, resolution between adjacent targets during automatic target tracking usually ranges somewhere between 0.03 to 0.05 NM. If multiple targets approach each other, resolution will become about 0.05 NM and this may cause the system to regard them as one target and thus to swap them or lose part of them. Such swapping or less of targets may also occur if the picture of the target being tracked is affected by rain/snow clutter returns or sea clutter returns or moves very close to land. [II] Intensity of echoes and the target tracking function The intensity of echoes and the tracking function have a correlationship, and thus the target will be lost if no echoes are detected during six scans in succession. If a lost target exists, therefore, radar gain must be increased to support detection of the target. If, however, radar gain is increased too significantly, sea clutter returns or other noise may be erroneously detected and tracked as a target, and resultingly, a false alarm may be issued. [III] Adverse effects of error sources on automatic tracking To execute accurate tracking, it becomes necessary first to appropriately adjust the [GAIN], [SEA] and [RAIN] dials of the radar so that the target to be acquired and tracked id clearly displayed on the radar display. Inappropriate settings of these adjustments reduce the reliability / accuracy of automatic tracking. 5-1
55.1 Preparation yyyyy5.1 PREPARATION This section explains the features of the target tracking and AIS functions, and the initial setting for using each function. Target Tracking Function (Option) The target tracking function calculates the course and speed of a target by automatically tracking the target's move. The target tracking function enables the automatic acquisition of targets by using the automatic acquisition zone function. The target tracking function also enables the simulation of the ship maneuvering method to avoid collisions by using the trial maneuver function. (NCA-877WA) If the mode is ground stabilization, SOG/COG used for own ship's information in target tracking. If the mode is sea stabilization, SPD (speed through the water) / HDG (heading) used for own ship's information in target tracking. Normal editionNCA-877A High performance editionNCA-877WA Maximum number of targets that can be tracked 30 100 Trial maneuver function Not provided Provided Note: ARPA Process Unit (NCA-877WA) or ATA Process Unit (NCA-877A) must be fitted on ships compliant to IMO. AIS (Automatic Identification System) function (Option) The AIS function shows the target’s information on the radar display, using other ship's information sent out from the AIS unit. Note: AIS Process Unit must be fitted on ships compliant to IMO. 5-2
5.1.1 Collision Avoidance Problems of Collision Avoidance in Navigation Marine collision avoidance is one of the problems that have been recognized from of old. Now, it will be described briefly who the collision avoidance is positioned among the navigational aid problems. The navigation pattern of all mobile craft constitutes a system with some closed loops regardless of the media through which the mobile craft travels, whether air, water, the boundary between air and water, or space. This pattern consists of two closed loops in principle, one of which is a collision with another mobile craft and the other is a loop of finding a right and safe way to reach a predeterminate destination. Fig. 5-1 shows the conceptual diagram of navigation pattern by MR. E.W. Anderson. The closed loop of collision avoidance is shown on the left side and the closed loop of finding a right course on the right side. Fig. 5-1 Navigation Pattern Marine Accidents and Collisions Among marine accidents, collision accidents have been highlighted as the tonnages and speeds of ships become higher along with the increase in traffic at sea. If a tanker carrying dangerous articles such as crude oil collides with any other vessel, then not only the vessels involved with the accident but other vessels in the vicinity, port facilities, inhabitants in the coastal area as well as marine resources may also suffer immeasurable damages and troubles. Collision accidents have a high percentage of the marine accidents that have occurred in recent years. To cope with these problems, any effective measures are needed and some equipment to achieve collision avoidance requirements have been developed at rapid strides. 5-3
55.1 Preparation yyyyyBasic Concept of Collision Avoidance There are two aspects in collision avoidance: collision prediction and avoidance. Collision prediction is to predict that two or more vessels will happen to occupy the same point at the same time, while collision avoidance is to maneuver vessels not to occupy the same point at the same time. In practical operation of vessels, a spot of collision has to be deemed to be a single point but a closed zone. This closed zone is conceptually defined as a CPA (Closest Point of Approach). In collision prediction, the time to be taken until a ship reaches the CPA is defined as a TCPA (Time to CPA). Fig. 5-2 shows a diagram caked “Collision Triangle”. Fig. 5-2 Collision Triangle 5-4
Relative Vector and True Vector From two points of view, collision prediction and avoidance, it is necessary to obtain the relative vector of other ship for prediction and the true vector of other ship for collision avoidance in order to grasp other ship’s aspect. The relationship between the relative vector and true vector is shown in Fig. 5-3. Both rough CPA and TCPA can be obtained easily from the relative speed vector of other ship. This method has an advantage that the risks of collision with all other ships within the radar range can be seen at a glance. On the other hand, the course and speed of other ship can easily be obtained from its true speed vector, enabling other ship’s aspect to be seen at a glance. Thus, the aspects of other ships (transverse, outsail, parallel run, reverse run, etc. ) as described in the act of prevention of collision at sea can be readily grasped. If there is a risk of collision with other ship, the operator can determine which rule to be applied and how to operate own ship.

A plotter is used to further enhance the radar functionality. The plotter is capable of plotting other positions of other ships in 3 to 6 minute intervals to monitor their movement. The plots of other ships represent their tracks relative to own ship, and it is shown whether there is a risk of collision, namely CPA and TCPA can be obtained. This method using a plotter is fairly effective, but the number of target ship, which is manually plotted, is limited and it takes several minutes to measure those. 5-5

AIS12 Up to 300 targets can be displayed in total of activated and sleeping AIS targets. Up to 100 activated AIS targets can be included in the total. If there are more AIS targets than the allowable maximum, they are displayed in the following priority order: 1. Numeric displayed target 2. Target of which CPA / TCPA is lower than the set value (Target as a dangerous ship for which an alarm has occurred) 3. Target in automatic activation zone 4. Activated AIS target 5. Target inside AIS filter 6. Target outside AIS filter If the number of targets at the same priority level exceeds the allowable maximum, they are displayed in the following priority order: 1. Association target 2. Activated AIS target 3. Sleeping AIS target 5-7
55.1 Preparation yyyyyThe vector of an AIS target is to be displayed with a vector over ground or over water, depending on the speed sensor setting and current offset setting. The type of the currently displayed vector can be confirmed by viewing the setting of the stable mode. When GND is displayed for the stability mode (upper left of the display on page 2-2): Vector over ground When Sea is displayed for the stability mode (upper left of the display on page 2-2): Vector over water When the vector of an AIS target is displayed with a vector over water, the system has converted the AIS target's vector over ground to the vector over water according to the data received from the AIS and the own ship's information. Note: When the AIS target's symbol is activated but the vector is not displayed, the following are probable causes of the trouble: COG/SOG is not yet input from the GPS. The selected speed sensor is malfunctioning. Types and Definitions of Association Target Symbols When a tracked target and an AIS target are decided as identical, it is displayed with either of the following symbols: Vector/Symbol Definition Remarks Priority for tracked targetAssociation target 12 Priority for AIS target Association target AIS12 Setting of Tracked Target Symbol Display This function switches the tracking target symbol display between on and off. Even if the tracking target symbol display is turned off, the data is retained. Procedures 1 Move the cursor onto the tracking target symbol display On / Off (TT / AIS information ⑨ on page 2-23), and press the [ENT] key. The tracking target symbol display will be set to on or off. Setting of AIS Target Symbol Display This function switches the AIS target symbol display between on and off.

5.1.3 Radar Display Vector Display A vector to represent a target’s predicted position can be presented in the True vector or Relative vector mode. In each mode, a vector length can be freely changed for a time interval of 1 to 60 minutes. To switch between the true vector mode and relative vector mode, press the [VECT R/T] key. [I] Vector Mode Selection True Vector Mode In the true vector mode, the direction of a target vector indicates the true course of the target and its vector length is proportional to its speed. In this mode, own ship’s vector is displayed as shown below. In this mode, the movements of other ships around own ship can be accurately and easily monitored. However, CPA Ring cannot appear in this mode. 5-9
55.1 Preparation yyyyyRelative Vector Mode The relative vector does not represent the true motion of the target, but its relative relation with own ship. This means that a target with its relative vector directed to own ship (passing through the CPA Limit ring) will be a dangerous target. In the Relative Vector mode, it can be seen at a glance where the CPA Limit of the dangerous target is. Therefore, the True / Relative mode shall optionally be used for the purpose of observation: the True vector mode for grasping the true aspect of a target, and the Relative vector mode for grasping a target’s closest point of approach (CPA). [II] Vector Length (Vector Time) The vector length of a target is proportional to its speed, and the vector time can be switched in a range of 1 to 60 minutes. The diagram below illustrates a vector length of a target for 6 minutes, and the tip of the vector represents the target’s position expected to reach 6 minutes later. Current positionFuture predicted position(6 min later in this example)HL Refer to Section 5.1.7 Setting Vectors for how to change the vector time. 5-10

Manually acquire the target to which particular attention should be paid, and get the other targets automatically acquired. If a new target appears exceeding the maximum number of targets, the manually acquired target is displayed even in the background until it gets out of the display. However, automatically acquired targets are canceled starting far distance from own ship. 5-18
5.2.2 Canceling Unwanted Tracked Targets [TGT CNCL] Unwanted tracked targets can be canceled one by one in the following cases: • Tracking is no longer necessary for targets with which vectors/symbols are displayed after being acquired and tracked. • The number of vectors on the radar display needs to be reduced for easy observation. When targets are to be re-acquired from the beginning, all the current vectors can also be canceled. Canceling targets one by one [TGT CNCL] Procedures 1 Put the cursor on the tracked target to the desired for canceling target, and press the [TGT CNCL] key. The vectors and symbols of the tracked targets will disappear, and only the radar video remain. Canceling all targets collectively [TGT CNCL] Procedures 1 Press the [TGT CNCL] key for 5 seconds. The vectors and symbols of all the targets will disappear, and only the radar videos remain. Note: When all the targets have been canceled, the system stops tracking them. Thus, you need to re-acquire targets in manual or automatic acquisition mode. Do not cancel all the targets unless otherwise required. 5-19
5.2 Target Tracking Operation yyyyy5.2.3 Tracked Target Data Display [TGT DATA] z When a target or own ship changes its course, or when a new target is acquired, its vector may not reach a given level of accuracy until 3 minutes or more has passed after such course change or target acquisition. Even if 3 minutes or more has passed, the vector may include an error depending upon the tracking conditions. Attention Type of Data Display (Target Information) 5 Target Data Target identification (TT ID) ID number of the target True bearing (BRG) 0.1° unit Range 0.01 NM unit Course 0.1° unit Speed 0.1 knot unit Closest point of approach (CPA) 0.01 NM unit Time to CPA (TCPA) 0.1 min unit Bow crossing range (BCR) 0.01 NM unit Bow crossing time (BCT) 0.1 min unit The target for which its numeric data is displayed is marked with a symbol " " to distinguish from other targets. If a target’s data is displayed, but without the symbol " " , such a target exists outside the currently displayed radar display. Method of Displaying Numeric Data [TGT DATA] Procedures 1 Put the cursor on the tracked target for which numeric data is to be displayed, and press the [TGT DATA] key. Then, the data of the designated target will appear, it will be marked with a symbol " ". The target data will remain on the radar display until the target is lost and its vector disappears, or until another target is designated. If a target with the mark " " is designated, only its true bearing and range will appear until its vector appears. 5-20

Selecting one of previously input ship names (Data Base) 5 Press the [numeric] key corresponding to the ship name to be selected. The selected ship name will be entered. * Data Base can contain 30 ship names. 5-22
5.2.6 Reference Target (Reference) The system can display the own ship's speed. To do so, it sets a reference target by tracking a target for which ground fixed. Attention z The reference target function is to be used if the own ship's speed cannot be displayed normally due to trouble such as a speed sensor malfunction. Do not use the reference target function except in emergencies. z If the speed or course of the own ship is changed or a new reference target is set, the displayed speed may take 3 minutes or more to reach the specified speed after the speed / course change or the setting. Even after 3 minutes or more has passed, the speed may differ from the specified speed depending on the tracking condition. z If a large radar echo such as a land target is set as a reference target, the vectors of the speed and other tracking targets will not be displayed correctly and may cause an accident. z If a sailing ship is set as a reference target, the vectors of the speed and other tracking targets will not be displayed correctly and may cause an accident. z If the REF. is selected for the speed sensor, the AIS function cannot be turned on. z If the reference target is lost or the target tracking function is stopped, the speed sensor is placed in manual mode MAN . z The loss of a reference target may have a major impact on the accuracy of the results for true speed and true course of the target and that own speed will be degraded. z The reference targets are only used for the calculation of true speed. 5-23

CPA / TCPA Alarm CAUTION Since these alarms may include some errors depending on the target tracking conditions, the navigation officer himself should make the final decision for ship operations such as collision avoidance. Making the final navigation decision based only on the alarm may cause accidents such as collisions. In the system, targets are categorized into two types: tracked / activate AIS targets and dangerous targets. The grade of danger can easily be recognized on the display at a glance. So the officer can easily decide which target he should pay attention to. It is not possible to switch off the tracked target visual alarm, unless tracking is ceased, or the alarm condition no longer applies. The types of target and alarm are shown below. CPA / TCPA Alarm Status Symbol on display Alarm characters Alarm sound Conditions Tracked target Activated AIS target (Off) (Off) • CPA > CPA LIMIT • 0 > TCPA • TCPA > TCPA LIMIT The symbol is displayed when one of the above conditions is met.

5.5 Alarm Display yyyyyAlarm for New Target Acquired in Automatic Acquisition Zone (New Target) CAUTION In setting an automatic acquisition zone, it is necessary to adjust the gain, sea clutter suppression and rain / snow clutter suppression to ensure that target echoes are displayed in the optimum conditions. No automatic acquisition zone alarms will be issued for targets undetected 5 The automatic acquisition function sets a zone in a range and issues an alarm when a new target (which is not yet acquired) goes into this zone. For the setting of an automatic acquisition zone, refer to " Acquiring Target " in Section 5.2.1. Alarm for New Target Acquired in Automatic Acquisition Zone Status Symbol on display Alarm characters Alarm sound Conditions New target in automatic acquisition zone Red Blinking New Target Beep sound (pipi-pipi) Alarm acknowledgeable The alarm is issued when a new target is acquired in the automatic acquisition zone. 12 Note: When an already acquired target goes into automatic acquisition zone, the alarm message is not displayed and the buzzer does not sound either. 5-44
Lost Target Alarm z If the gain, sea clutter suppression, rain/snow clutter suppression are not adjusted adequately, the lost target alarm may be easily generated. So such adjustments should be mad carefully. When it is impossible to continue tracking any acquired and tracked target, or the data of AIS target cannot received for a specified time, the LOST alarm will be generated. The typical causes for alarm generation are shown below, but not limited to the following: • The target echo is very weak. • The target is shadowed by a shore or a large ship and its echo is not received. • The target echo is blurred by sea clutter returns. If a target under tracking goes out of a range of 32 nm and can no longer be tracked, it is canceled without a lost target alarm. Lost Target Alarm Status Symbol on display Alarm characters Alarm sound Conditions Lost target Red Blinking Lost Beep sound (pee) Alarm acknowledgeable The alarm will sound once when a lost target symbol is displayed. Gyro Set Alarm The GYRO I/F in this system receives signals from a gyro. Even if the power is turned off, the system will follow up the gyro. However, the system stops the follow-up operation when the power of the master gyro is turned off or when any trouble occurs to the line. When the power of the master gyro is recovered, the Set Gyro alarm will be generated. If this alarm occurs, set the gyro.

5.7 Trial Maneuvering yyyyy5.7 TRIAL MANEUVERING (TRIAL MANEUVER) 5 z Trial maneuvering is to simulate own ship’s course and speed in the conditions that the course and speed of a target ship are unchanged as they are. As the situation is different from any actual ship maneuvering, set values with large margins to CPA Limit and TCPA Limit. Attention The trial maneuvering is the function of simulating own ship’s course and speed for collision avoidance when a dangerous target appears. When the own ship's course and speed are entered in manual mode, the trial maneuvering function checks if pre-acquired or pre-activated targets are dangerous. The ranges of course and speed to be entered manually: Course: 360° (in 0.1° intervals)........................................................................... [EBL] dial Speed: 0 to 100 kn (in 0.1 kn steps)................................................................... [VRM] dial 5-56
Trial Maneuvering in the True Vector Mode In the True Vector mode, calculations are performed according to the values set by Trial Speed, Trial Course and other features, and the result is displayed as a bold-line that represents the change of own ship’s vector as shown in the figure below (an example of the course changed to the right). In this figure, the dangerous target forward left becomes safe as a result of simulation. The tracked target information indicates the current CPA and TCPA values regardless of the result of simulation. 5-57
5.7 Trial Maneuvering yyyyyTrial Maneuvering in the Relative Vector Mode The result of Trial maneuvering in the Relative Vector mode is shown by a change in target vector. In the figure below (in the same conditions as in the True Vector mode in the previous page), it is seen that the acquired target is a dangerous one because its vector is crossing the CPA RING. 5 The above figure shows that the relative vector of the target has changed as shown in the figure as a result of simulation (course and speed), so that the symbol color is changed into “White”, a safe target. Irrespective of the simulation results, the current CPA and TCPA values are shown in the tracked target information just like when the true vector mode is active. The course change of own ship is displayed as a dotted-line. Better information is provided by using relative motion and sea stabilization. 5-58
Operation of Trial Maneuvering Function Procedures 1 Press the [TT MENU] key. 2 Open the Trial Maneuver menu by performing the following menu operation. 3. Trial Maneuver 3 Press the [1] key.

When Trial Function is set to on, the character " T " indicating trial maneuvering blinks in the own ship display field of the radar display. 4 Set values for Course by turning the [EBL] dial, and for Speed by turning the [VRM] dial. 5 Set other characteristics. Vector Time :Vector time (1 to 60 min) Time to Maneuver :Time until trial maneuvering is started (0 to 30 min) Own Ship Dynamic Trait> :Dynamic trait of the own ship → Reach :Range from when steered to when the ship beings to turn (0 to 2000 m) → Turn Radius :Turning radius (0.10 to 2.00 nm) → Acceleration :Acceleration (0.0 to 100 kn/min) → Deceleration :Deceleration (0.0 to 100 kn/min) For inputs to the value input screen, refer to Section 3.3.4. Dangerous target symbols are displayed in red and safe target symbols in white. * Vector Time is valid only when Trial Function is set to on. If it is off, the vector time before trial maneuvering is displayed. Time until the start of trial maneuvering is counted down immediately after the input. The acceleration and deceleration are influenced depending on the relationship between the current speed and the input speed for trial maneuvering. If 0.0 kn/min is set for Acceleration when the speed for trial maneuvering is faster than the current speed, or for Deceleration when the speed for trial maneuvering is slower than the current speed, the system performs simulation on the assumption that the speed is changed immediately after the time set for Time to Maneuver . Cancellation 1 Press the [1] key while the Trial Maneuver menu is displayed. The Trial Function will be set to on or off. Off :The trial maneuvering function is turned off. 5-59

The radar operator has a role of interpreting the radar displays to provide his best aid in maneuvering the ship. For this purpose, the operator has to observe the radar displays after fully understanding the advantages and disadvantages that the radar has. For better interpretation of radar display, it is important to gain more experiences by operating the radar equipment in fair weathers and comparing the target ships watched with the naked eyes and their echoes on the radar display. The radar is mainly used to monitor the courses of own ship and other ships in open seas, to check buoys and other nautical marks when entering a port, to measure own ship’s position in the coastal waters relative to the bearings and ranges of the shore or islands using a chart, and to monitor the position and movement of a heavy rain if it appears on the radar display. Various types of radar display will be explained below. 6.1 RADAR WAVE WITH THE HORIZON Radar beam radiation has the nature of propagating nearly along the curved surface of the earth. The propagation varies with the property of the air layer through which the radar beam propagates. In the normal propagation, the distance (D) of the radar wave to the horizon is approximately 10% longer than the distance to the optical horizon. The distance (D) is given by the following formula: D=2.23( h2h1 +)(nm) h1: Height (m) of radar scanner above sea level h2: Height (m) of a target above sea level Figure 6.1 is a diagram for determining the maximum detection range of a target that is limited by the curve of the earth surface in the normal propagation. 6-1
6.1 Radar Wave with the Horizonyyyyyy D (nm) 6 Height of Target Height of Radar Scanner Detective Range Figure 6.1 When the height of own ship’s scanner is 10 m for instance, (a) A target that can be detected at the radar range of 64 nm on the radar display is required to have a height of 660 m or more. (b) If the height of a target is 10 m, the radar range has to be approx. 15 nm. However, the maximum radar range at which a target can be detected on the radar display depends upon the size of the target and the weather conditions, that is, the radar range may increase or decrease depending upon those conditions. 6-2
6.2 STRENGTH OF REFLECTION FROM THE TARGET The signal intensity reflected from a target depends not only on the height and size of the target but also on its material and shape. The echo intensity from a higher and larger target is not always higher in general. In particular, the echo from a coast line is affected by the geographic conditions of the coast. If the coast has a very gentle slop, the echo from a mountain of the inland appears on the radar display. Therefore, the distance to the coast line should be measured carefully. Mountain displayedon the radar displaySea shore line not displayedon the radar display.HL Figure 6.2 Table 6.1 shows the graph indicating the relation between the target detection distance and the radar reflection cross-sectional area (RCS) with regard to the type and the height of the target in a situation in which the weather is good, the sea state is calm and the radio wave propagation is normal. As revealed by this table, even on the same sea shore line, detection distance greatly differs depending on the height of the target from the surface of the sea. Furthermore, because the target detection distance is greatly influenced by the shape and material of the target and environmental conditions, such as the sea state, weather, and radio wave propagation, caution should be taken when detecting distance of target. 6-3

6.3 SEA CLUTTER AND RAIN AND SNOW CLUTTER In addition to the echo required for observing ships and land radar video image also includes unnecessary echo, such as reflection from waves on the sea surface and reflection from rain and snow. Reflection from the sea surface is called "sea clutter," and reflection from rain and snow is called "rain and snow clutter," and those spurious waves must be eliminated by the clutter rejection function. [I] Sea clutter Sea clutter appears as an image radiating outwardly from the center of the radar display and changing depending on the size and the shape of waves. Generally, as waves become larger, image level of the sea clutter is intensified and the clutter far away is also displayed. When waves are large and the sea clutter level is high, it is difficult to distinguish sea clutter from a small boat whose reflection intensity is weak. Accordingly, it is necessary to properly adjust the sea clutter rejection function. Table 6.2 shows the relation between the sea state (SS) showing the size of waves generated by wind and the radar's detection probability. Table 6.2 Sea state and probability of target detection RCS SS1 to 2 SS2 to 3 SS3 to 4 SS4 to 50.1m2V V-M M-NV 0.5 m2V V V-M M-NV 1 m2V V V V-M S band radar (probability to detect a target at a distance of 0.4 NM) RCS SS1 to 2 SS2 to 3 SS3 to 4 SS4 to 51m2V-M M-NV 5 m2V V-M M-NV 10 m2V V V V-M X band radar (probability to detect a target at a distance of 0.7 NM) V: Detection probability of 80 % M: Detection probability of 50 % NV: Detection probability of less than 50 % 6-5
6.3 Sea Clutter and Rain and Snow Clutteryyyyyy As shown in Table 6.3, the number of SS increases as the wind speed becomes high and the waves become large. Table 6.2 reveals that detection probability decreases from V (80 %) to NV (less than 50 %) as the number of SS increases. Therefore, even if the sea state is calm and a target clearly appears on the radar display, when the sea state becomes rough, target detection probability decreases resulting in difficulty of target detection by the radar. Table 6.3 Relation between Douglas sea state and average wind speed and significant wave height Sea state Average wind speed (kn) Significant wave height (m) 0 <4 <0.2 1 5-7 0.6 2 7-11 0.9 3 12-16 1.2 4 17-19 2.0 5 20-25 3.0 6 26-33 4.0 Significant wave height: an average of top N/3 higher waves when the number of waves detected within a constant time duration is N 6 For example, in the case of a standard marine buoy, RCS of X band radar is 5 m2 as shown in Table 6.1. When observing such a target in the sea state (SS3) in which significant wave height exceeds 1.2 meters, detection probability is M-NV, as shown in Table 6.2, which indicates 50 % or less. [II] Rain and snow clutter Rain and snow clutter is a video image that appears in a location where rain or snow is falling. The image changes according to the amount of rain (or the amount of snowfall). As precipitation increases, the image of rain and snow clutter becomes intensified on the radar display, and in the case of localized heavy rain, an image similar to the image indicating land is displayed in some cases. Furthermore, because radio waves tend to attenuate due to rain and snow, the ability to detect a target in the rain and snow clutter or a target beyond the rain and snow clutter may decrease. The amount of attenuation depends on the transmission frequency, antenna beam width, and the pulse length. Figure 6.3 and Figure 6.4 show examples in which detection distance is reduced due to the influence of precipitation. Because of this, a target, which clearly appeared up to 10 NM by an X band radar (pulse width of 0.8 μs) when it was not raining, may become dimly visible up to 5 NM when the amount of rain becomes 4 millimeters per hour. Furthermore, when comparing the X band radar with the S band radar, target detection distance decreases less when an S band radar is used, which means it is influenced less by precipitation. 6-6

6.3 Sea Clutter and Rain and Snow Clutteryyyyyy[III] Coping with sea clutter and rain and snow clutter When the weather is bad and the ocean is rough, the use of an S band radar is effective because the radar is not influenced by sea clutter so much and attenuation due to rain drops is small. When an X band radar is used, reducing the pulse width will reduce the influence by spurious waves, and also the spurious wave rejection function effectively works; therefore, the use of short pulse is effective when the weather is bad. By using image processing functions PROC 1 to 3, it is expected that spurious waves are further suppressed. Since optimal settings for those items can be automatically made by using the function mode, it is recommended that STORM or RAIN be used by selecting the function mode when the weather is bad. For details of the function mode, see Chapter 3.9. However, these functions may make some targets invisible, particularly targets with higher speeds. 6 6-8
6.4 FALSE ECHOES The radar observer may be embarrassed with some echoes that do not exist actually. These false echoes appear by the following causes that are well known: [I] Shadow When the radar scanner is installed near a funnel or mast, the echo of a target that exists in the direction of the funnel or mast cannot appear on the radar display because the radar beam is reflected on the funnel or mast. Whether there are some false echoes due to shadows can be checked monitoring the sea clutter returns, in which there may be a part of weak or no returns. Such shadows appear always in the same directions, which the operator should have in mind in radar operation. [II] Side Lobe Effect A broken-line circular arc may appear at the same range as the main lobe of the radar beam on the radar display. This type of false echo can easily be discriminated when a target echo appears isolated. (See Figure 6.5) Figure 6.5 [III] False Echo by Secondary Reflection When a target exists near own ship, two echoes from the single target may appear on the radar display. One of those echoes is the direct echo return from the target and the other is the secondary reflection return from a mast or funnel that stands in the same direction as shown in Figure 6.6. Figure 6.6 6-9
6.4 False Echoesyyyyyy[IV] False Echo by Multiple Reflection When there is a large structure or ship with a high vertical surface near own ship as shown in Figure 6.7, multiple refection returns may appear on the radar display. These echoes appear in the same intervals, of which the nearest echo is the true echo of the target. Figure 6.7 [V] Second Time Echoes The maximum radar detection range depends upon the height of the scanner and the height of a target as described in the section of “The Horizon for Radar Beam Radiation”. If a so-called “duct” occurs on the sea surface due to a certain weather condition, however, the radar beam may propagate to a abnormally long distance, at which a target may be detected by the radar. For instance, assuming that the pulse length is MP3 (on the repetition frequency of 1400 Hz), the first pulse is reflected from a target at about 58 NM or more and received during the next pulse repetition time. In this case, a false echo (second time echo) appears at a position that is about 58 NM shorter than the actual distance. If the false echo appears at 5 NM on the radar display, the true distance of the target is 5+58=63 NM. On the pulse length is SP1 (on the repetition frequency of 2250 Hz), a false echo may appear at a position that is about 36 NM shorter than the actual distance. 6 This type of false echo can be discriminated by changing over the range scale (the repetition frequency), because the distance of the target changes accordingly. If second time echo is appeared, the use of Economy mode in PRF menu is effective. Otherwise, Stagger Trigger menu set to on. (See section 3.8.3) 6-10
[VI] Radar Interference When another radar equipment using the same frequency band as that on own ship is near own ship, a radar interference pattern may appear on the radar display. This interference pattern consists of a number of spots which appear in various forms. In many cases, these spots do not always appear at the same places, so that they can be discriminated from the target echoes. (See Figure 6.8) Figure 6.8 If radar equipment causing an interference pattern and this radar are of the same model, their transmitting repetition frequency is nearly the same. As a result, interference patterns may be displayed concentrically. In this case, the interference patterns cannot be eliminated by using only the interference reflector function, so press [TX/PRF] key several times to fine-tune the transmitting repetition frequency. An interference suppressing effect can be heightened by applying a different transmitting repetition frequency to the interference pattern source radar and this radar. 6-11
6.5 Display of Radar Transponderyyyyyy6.5 DISPLAY OF RADAR TRANSPONDER (SART) The SART (Search and rescue Radar Transponder) is a survival device authorized by the GMDSS (Global Maritime Distress and Safety System), which is used for locating survivors in case that a distress accident occurs at sea. The SART is designed to operate in the 9 GHz frequency band. When receiving the 9 GHz radar signal (interrogating signal) transmitted from the radar equipment on a rescue ship or search aircraft, the SART transmit a series of response signals to inform the distress position to the rescue and search party. * This radar provides a shortcut item to make settings for SART signal reception. Execution of this item automatically switches to the setting for SART reception. It also functions for detect the beacon or target enhancer. Procedures 1 Press [RANGE +] or [RANGE -] key to set the radar range to 6 NM or 12 NM. 2 Press [RADAR MENU] key twice, and then set the SART display mode according to the procedures below. 6 2. RADAR Menu → 1. Process Setting → 9. SART On : SART ON Off : SART OFF With the SART display mode set to ON, settings as shown below are made automatically. (1) Sea clutter control: Minimum (Most counterclockwise) (2) AUTO SEA function: OFF (3) Rain and Snow Clutter Control (RAIN): minimum (4) Auto Rain and Snow Clutter function (AUTO RAIN): OFF (5) TUNE control: No tuning (to weaken clutter echoes) (6) Interference rejecter (IR): OFF (7) PROCESS: OFF 6-12
[Example of Display] z When the SART function is set to ON, small targets around own ship will disappear from the radar display. So it is necessary to exercise full surveillance over the conditions around own ship by visual watch in order to avoid any collision or stranding. If two or more sets of radar equipment are installed on own ship, use one set of 9 GHz band radar for detection of the SART signal and operate others as normal radars for avoiding collision, monitoring targets around own ship, and checking on own ship’s position and avoidance of stranding. After end of detecting the START signal, turn the START display off. Then the radar returns normally to the nautical mode. Attention 6-13

Precautions in Mounting the Cover When the cover is removed for regular checkup and replacement of parts and refitted after such work, the procedures of fastening bolts shall be taken with the following precautions: (a) The proper fastening torque of the fitting bolts (M8) is 1176 to 1470 N•cm (120 to 150kgf•cm) (which makes the inside water-tight and protects the packings against permanent compressive strain). The packings start producing from the cover at a torque of approximately 1470N•cm (150kgf•cm). Do not fasten the bolts with a torque exceeding the specified value. Otherwise, the screws may be broken. (b) Use an offset wrench of 11 mm × 13 mm or a double-ended wrench of 13 mm × 17 mm (not longer than 200 mm). (c) Screw all the bolts by hand first to prevent them playing, then fasten them evenly in order not to cause one-sided fastening. (Fasten the bolts with 25% of the required torque at the first step.) *: Fasten the bolts in the diagonal order. 8-3
8.2 Maintenance on each Unit yyyyyyyy(1) Radiator z If the radiator front face (radiation plane) is soiled with smoke, salt, dust, paint or birds’ droppings, wipe it with a piece of soft cloth wetted with alcohol or water and try to keep it clean at all times. Otherwise, radar beam radiation may attenuate or reflect on it, resulting in deterioration of radar performance. z Never use solvents of gasoline, benzine, trichloroethylene and ketone for cleaning. Attention Check up and clean the radiator. (2) Rotating section (a) Supply Oil Seal An scanner unit with a grease nipple needs grease supply. Remove the cap of the grease nipple on the front of the radiator support, and supply grease with a grease gun. Make the oiling every six months. The oil quantity shall be approximately 100 g, which is as much as the grease comes out of the oil seal. Use the grease of Mobilux 2 of Mobil Oil. 8 (b) Oiling gears Apply grease evenly to the tooth surfaces of the main shaft drive gear and the encoder drive gear with a spreader or brush. Oiling in short intervals is more effective to prevent the gears from wear and tear and extend their service life, but oil at least every six months. Use Mobilux2 of Mobile Oil. (c) Mounting legs Check the mounting legs and mounting bolts of the scanner unit case for corrosion at intervals and maintain them to prevent danger. Apply paint to them once a half year because painting is the best measure against corrosion. 8-4

9.1 FAULT FINDING In case of semiconductor circuits, it is deemed that there are few cases in which the used semiconductor devices have inferior quality or performance deterioration except due to insufficient design or inspection or by other external and artificial causes. In general, the relatively many causes are disconnection in a high-value resistor due to moisture, a defective variable resistor and poor contact of a switch or relay. Some troubles are caused by defective parts, imperfect adjustment (such as tuning adjustment) or insufficient service (such as poor cable contact). It will also be effective to check and readjust these points. 9.1.1 List of Alarms and other Indications The system automatically recognizes an internal alarm and displays the alarm message.

A-9 III REFERENCE Preheat Time after Change of Connection Pattern After the current interswitch connection pattern has been changed, operation needs to wait until the system is ready. This is because the preheat time varies depending on the previous connection of the scanner unit and display unit. The wait time is necessary for protecting the electronic tubes that emit radio waves. a) When not changed to a new connection pattern : Preheating not required b) When changed to a new connection pattern and an scanner unit had been used before the change : Preheating not required c) When changed to a new connection pattern and an scanner unit had not been used before the change : Preheating required Notes on Changing Connection Pattern An attempt to change to another connection pattern immediately after the completion of connection pattern change may fail. This is because internal processing still needs some preparation time upon completion of connection pattern change. Let several seconds pass between connection pattern change operations. Notes on Connecting Slave Display Unit Before a slave display unit can be placed in transmission state, the master display unit must be placed in transmission state. If the master display unit is moved from the transmission state to the transmission standby state, the slave display unit is forcibly placed in transmission standby state. When they are in transmission standby state, MTR Standby is shown in the alarm indication (Brilliance / alarm on page 2-9), and the alarm sounds. A slave display unit cannot control tune. Tune is controlled by the master display unit. Slave is shown in the transmitter pulse length (upper left of the display on page 2-2). Range change for a slave display unit is limited by the range and pulse length / repetition frequency of the master display unit. As a rule, a greater range than the range of the master display unit cannot be set for a slave display unit. However, if the transmitter pulse length of a slave display unit is identical to the master display unit's and the repetition frequency is within the master display unit's, a greater range than the master display unit's can be selected for the slave display unit. When the master display unit narrows the range or changes the transmitter pulse length, the range of the slave display unit may be forcibly changed. In this case, Master Range CHG is shown in the alarm indication (Brilliance / alarm on page 2-9), and the alarm sounds.
