JMA-9100 Instruction Manual > 5.OPERATION OF TARGET TRACKING AND AIS > 5.1 PREPARATION5－95[2] Relative Vector ModeThe 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).Fig 5-5: Relative Vector5.1.3.3 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.Fig 5-6: Vector LengthRefer to Section 5.1.6 "Setting Vectors (Vector Time)".

JMA-9100 Instruction Manual > 6.TRUE AND FALSE ECHOES ON DISPLAY > 6.1 RADAR WAVE WITH THE HORIZON6－16The 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 HORIZONRadar 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: [NM]: Height (m) of radar scanner above sea level: Height (m) of a target above sea levelFig 6-2 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.Fig 6-1: RADAR wave with the horizonD2.23h1h2+()=h1h2DEarthh1h2Radar Targets

A target that can be detected at the radar range of 64 nm on the radar displayis required to have a height of 660 m or more.ii. 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 theradar display depends upon the size of the target and the weather conditions,that is, the radar range may increase or decrease depending upon thoseconditions.

JMA-9100 Instruction Manual > 6.TRUE AND FALSE ECHOES ON DISPLAY > 6.2 STRENGTH OF REFLECTION FROM THETARGET6－366.2 STRENGTH OF REFLECTION FROM THE TARGETThe 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.(Fig 6-3) Therefore, the distance to the coast line should be measured carefully.Fig 6-3: Sea shore line which is not displayedTable 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.Mountain displayedon the radar displaySea shore line not displayedHL

JMA-9100 Instruction Manual > 6.TRUE AND FALSE ECHOES ON DISPLAY > 6.3 SEA CLUTTER AND RAIN AND SNOWCLUTTER6－566.3 SEA CLUTTER AND RAIN AND SNOW CLUTTERIn 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.a. Sea clutterSea 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 detectionS band radar (probability to detect a target at a distance of 0.4 NM)RCS SS1～2SS2～3SS3～4SS4～50.1m2 Vii.

6－6JMA-9100 Instruction Manual > 6.TRUE AND FALSE ECHOES ON DISPLAY > 6.3 SEA CLUTTER AND RAIN AND SNOW CLUTTERAs shown in Table 6-2, 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.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. b. Rain and snow clutterRain 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. Fig 6-4 and Fig 6-5 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 0.8μs) 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.Table 6-3： Relation between Douglas sea state and average wind speed and significant wave heightSea state Average windspeed (kn)Significant waveheight (m)ii.

6－8JMA-9100 Instruction Manual > 6.TRUE AND FALSE ECHOES ON DISPLAY > 6.3 SEA CLUTTER AND RAIN AND SNOW CLUTTERc. Coping with sea clutter and rain and snow clutterWhen 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 PROCl 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 Section 3.9 "USE FUNCTION KEY [USER]".However, these functions may make some targets invisible, particularly targets with higher speeds.

JMA-9100 Instruction Manual > 6.TRUE AND FALSE ECHOES ON DISPLAY > 6.4 FALSE ECHOES6－966.4 FALSE ECHOESThe 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:a. ShadowWhen 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.b. Side Lobe EffectA 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 Fig 6-6) Fig 6-6: False echo HL

6－10JMA-9100 Instruction Manual > 6.TRUE AND FALSE ECHOES ON DISPLAY > 6.4 FALSE ECHOESc. False Echo by Secondary ReflectionWhen 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 Fig 6-7.Fig 6-7: False echo by secondary reflectiond. False Echo by Multiple ReflectionWhen there is a large structure or ship with a high vertical surface near own ship as shown in Fig 6-8, 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. Fig 6-8: False echo by mutiple reflection e. Second Time EchoesThe maximum radar detection range depends upon the height of the scanner and the height of a target as described in the Section 6.1 "RADAR WAVE WITH THE HORIZON". 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.Radar scannerFunnelHLDirect microwaveSecondary reflectionof microwaveActual targetFalse echo from funnelHL

JMA-9100 Instruction Manual > 6.TRUE AND FALSE ECHOES ON DISPLAY > 6.4 FALSE ECHOES6－116For 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.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 "Set Scanner Unit (TXRX Setting)").f. Radar InterferenceWhen 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 Fig 6-9)Fig 6-9: Radar interferenceIf 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 ine-tune the transmitting repetition frequency.( See Section 3.8.3 "Set Scanner Unit (TXRX Setting)")An interference suppressing effect can be heightened by applying a different transmitting repetition frequency to the interference pattern source radar and this radar.HL HL

JMA-9100 Instruction Manual > 8.COUNTERMEASURE FOR TROUBLE ... > 8.1 ROUTINE MAINTENANCE8－188.1 ROUTINE MAINTENANCEFor operating the radar equipment in the good conditions, it is necessary to make the maintenance work as described below. If maintenance is made properly, troubles will reduce. It is recommended to make regular maintenance work.Common points of maintenance for each unit are as follow:•Clean the equipment.Remove the dust, dirt, and sea water rest on the equipment cabinet with a piece of dry cloth.Especially, clean the air vents with a brush for good ventilation. • Never carry out internal inspection or repair work of the equipment by users. Inspection or repair work by unauthorized personnel may result in fire hazard or electric shock. Ask the nearest branch, business office or a dealer for inspection and repair.• Turn off the main power before maintenance work. Otherwise, an electric shock may result.• Turn off the main power before cleaning the equipment. Especially, make sure to turn off the indicator if a rectifier is used. Otherwise, equipment failure, or death or serious injury due to electric shock may result, because voltage is outputted from the rectifier even when the radar is not operating.

Precautions in Mounting the CoverWhen 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:1) 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.2) Use an offset wrench of 11 mm X 13 mm or a double-ended wrench of 13 mm X 17 mm (not longer than 200 mm).3) 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.)• Turn off the main power source before starting maintenance. Otherwise, an electric shock or injury may be caused.• Do not touch the radiator. Even if the power is turned off, the radiator may be rotated by the wind.• Turn "OFFi" the safety switch to stop the scanner unit. (Refer to Section 1.4 "EXTERIOR DRAWINGS".) Otherwise, you may be injured if touching the rotating scanner unit by accident.i. After the work, turn "ON" the scanner unit safety switch.• Do not touch the radiator. Even if the power is turned off, the radiator may be rotated by the wind.*Fasten the bolts in the diagonal order.

JMA-9100 Instruction Manual > 8.COUNTERMEASURE FOR TROUBLE ... > 8.2 MAINTENANCE ON EACH UNIT8－38b. Radiator　　　　　　　　Check up and clean the radiator.• 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.• Never use solvents of gasoline, benzine, trichloroethylene and ketone for cleaning. Otherwise, the radiation plane may deteriorate.②①③④⑤⑥⑦⑧Tightening torque : 120 to 150 kgf/cm4-M8 (stainless steel) boltTightening torque : 120 to 150 kgf/cm8-M8 (stainless steel) bolt②①③④②①③④Bolt Tightening Procedure of NKE-1125/1129/2254 CoverBolt Tightening Procedure of NKE-1130 /1139 CoverBolt Tightening Procedure of NKE-2103 CoverTightening torque : 120 to 150 kgf/cm4-M8 (stainless steel) boltAttention
