3-143 3.4 BASIC OPERATIONS yy y3.4.5 Control Sensitivity [GAIN] Procedures 1 Control noise on the radar display by turning the [GAIN] control until targets can be easily observed. Turning [GAIN] control clockwise increases sensitivity. Turning [GAIN] control counterclockwise decreases sensitivity. Turning the [GAIN] control clockwise increases receiving sensitivity and extends the radar observation range. If the sensitivity is too high, the receiver noise increases reducing the contrast between the targets and the background video. As a result, the targets become obscure on the radar display. To observe densely crowded targets or short-range targets, turn the [GAIN] control counterclockwise to reduce the sensitivity so that the targets are easy to observe. However, be careful not to overlook important small targets. Note: After gain adjustment with software button once, push the [GAIN] knob for gain adjustment with [GAIN] knob. 3.4.6 Suppress Sea Clutter [SEA] Procedures 1 Control the sea clutter returns on the radar display by turning the [SEA] control until targets can be easily observed. Turning [SEA] control clockwise suppresses sea clutter returns. Turning [SEA] control counterclockwise intensifies sea clutter returns. The sea clutter suppression function suppresses sea clutter returns by decreasing the receiving sensitivity on a short range. Turning the [SEA] control clockwise heightens the effect of sea clutter suppression. However, be careful that excessive suppression causes low signal-strength targets such as buoys and boats to disappear from the radar display. Note: After STC adjustments with software button once, push the [SEA] knob for STC adjustment with [SEA] knob. When using the [SEA] function, never set the suppression level too high canceling out all image noises from the sea surface at close range. Detection of not only echoes from waves but also targets such as other ships or dangerous objects will become inhibited. When using the [SEA] function, make sure to choose the most appropriate image noise suppression level. CAUTION
3-153.4.7 Suppress Rain/Snow Clutter [RAIN] Procedures 1 Control the rain/snow clutter returns on the radar display by turning the [RAIN] control until targets can be easily observed. Turning [RAIN] control clockwise suppresses rain/snow clutter returns. Turning [RAIN] control counterclockwise intensifies rain/snow clutter returns. When the [RAIN] control is turned clockwise, the rain/snow clutter suppression function suppresses rain/snow clutter returns and gets targets hidden by rain/snow clutter returns to appear on the radar display. However, be careful that excessive suppression may cause small targets to be overlooked. Since the rain/snow clutter suppression function also has the effect of suppressing sea clutter, the suppression efficiency improves when the [RAIN] control is used with the [SEA] control. In general, turn the [RAIN] control fully to the left. Note: After rain adjustment with software button once, push the [RAIN] knob for rain adjustment with [RAIN] knob. When using the [RAIN] function, never set the suppression level too high canceling out all image noises from the rain or snow at the close range. Detection of not only echoes from the rain or snow but also targets such as other ships or dangerous objects will become inhibited. When using the [RAIN] function, make sure to choose the most appropriate image noise suppression level. CAUTION
3-163 3.4 BASIC OPERATIONS yy y3.4.8 Reject Radar Interference [IR] Procedures 1 Place the cursor over [IR]icon at the upper right of the radar display with trackball and then press [ENTER] key.

5-1 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.
5-25.1 RADAR WAVE WITH THE HORIZON yyyyy55.1 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 5. 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. Figure 5.1 Radar Earth Targets
5-3 Figure 5.2 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. Height of Radar Scanner Detective Range Height of Target D (nm)
5-45.2 STRENGTH REFLECTION FROM THE TARGET yyyyy55.2 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. HL Figure 5.3 Quay displayed on the radar display River side not displayed on the radar display.
5-55.3 SEA CLUTTERS When the sea surface ruffles, bright echo returns spread around the center of the radar display. The higher the waves are, the echo returns are larger. Swirling currents may appear as a smooth line like a coastal line.
5-65.4 FALSE ECHOES yyyyy55.4 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 5.4) Figure 5.4 [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 5.5. Figure 5.5 Direct microwaveRadar scanner Funnel Actual target Secondary reflection of microwave False echo from funnel
5-7[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 5., 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 5.6 [V] Abnormal Propagation 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 radar range is 4 km (on the repetition frequency of 4000 Hz), the first pulse is reflected from a target at about 37.5 km or more and received during the next pulse repetition time. In this case, a false echo appears at a position that is about 37.5 km shorter than the actual distance. If the false echo appears at 5 NM on the radar display, the true distance of the target is 2+37.5=39.5 km. 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.
5-85.4 FALSE ECHOES yyyyy5[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 5.7) Figure 5.7 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] 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.
5-95.5 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. The setting for SART signal reception (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 Yesterday (AUTO RAIN): minimum (5) TUNE control: No tuning (to weaken clutter echoes) (6) Interference rejector (IR): OFF Figure 5.8 [Example of Display] SART code Position of SART Position of the rescue craft Other ships Landz When you set the radar to detect the SART signal, 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, adjust the radar normally again. Then the radar returns normally to the nautical mode. Attention

6-16.1 ROUTINE MAINTENANCE WARNING 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. For 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.
6-26.2 MAINTENANCE OF EACH UNIT yyyyyy66.2 MAINTENANCE ON EACH UNIT Scanner Unit NKE-316 WARNING Turn off the main power source before starting maintenance. Otherwise, an electric shock or injury may be caused. Turn off the main power if you need to be near the scanner unit for maintenance or inspection purposes. Direct exposure to electromagnetic waves at close range in death or serious injury. Set the safety switch for stopping the scanner unit to the OFF position. Otherwise, an accidental contact with the rotating scanner unit may cause injury.
6-3 CAUTION Do not put watches, clocks, or magnetic cards close to the modulator unit since this unit holds magnetrons having strong magnetic force. Failure or data destruction of the above devices may result. After finishing the maintenance work, reset the safety switch to the ON position. 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.

6-5(1) Radiator Check up and clean the 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. Otherwise, the radiation plane may deteriorate. Attention
6-66.2 MAINTENANCE OF EACH UNIT yyyyyy6(2) Rotating section (a) Supply Oil Seal When there is not a grease nipple, the replenishment of grease oil is unnecessary. Remove the cap on the grease nipple located on the side of the X band radar or on the front of S band radar at which the radiator is supported, and 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. (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.
