If the indicated value becomes extremely short against the bar length checked at the initial time, it is necessary to request for checking of the transmitter system by a service engineer.
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● Checking procedure ３ ① Read a current value A on the bar indicator. ② Referring to the Calibration Curve I, obtain a relative attenuation d(B) for the initial bar indicator length B that is specified in the INFORMATION LABEL. ③ Then, obtain a relative attenuation d(A) for the value A referring to the Calibration Curve I.
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● (Example) Assuming that the initial bar indication is B = 8 and the current bar indication A = 6, the relative attenuation is d(B) = 3.5 dB, d(A) = 7 dB. Thus, d(A) - d(B) = 3.5dB. This clearly indicates that the current transmission output power is attenuated by approximately 3.5 dB.
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● 3 Checking Receiver System The maximum range of the PM pattern on display indicates a deterioration of the sensitivity of the receiver system. Checking Procedure ３ ⑤ Measure the PM pattern displayed on the display using the VRM of the maximum range ‘max’ from the PPI sensor.
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● (Example) Assuming that the maximum range of the initial PM pattern is rBmax = 18 NM according to the INFORMATION LABEL, and if that of the current PM pattern is rAmax = 16 NM, the deterioration value is ∆R (rmax) = 5dB, referring to Calibration Curve II. This means that the receiver system has sensitivity deterioration of approximately 5dB.

● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● Guard Zone Alarm [GUARD ZONE]･･････････････････････････ CAUTION In setting a guard zone, it is necessary to adjust radar tuning, gain, sea clutter suppression and rain/snow clutter suppression to ensure that target echoes are displayed in the optimum conditions. The guard zone alarm is not generated for the targets that are not detected by radar.
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● Lost Target Alarm [LOST TARGET]･･････････････････････････ Attention If the radar tuning, gain, sea clutter suppression and rain/snow clutter suppression are not appropriate, the lost target alarm may be generated frequently, so that adjustments should be made carefully. When it is impossible to continue tracking any acquired and tracked target, the LOST target alarm will be generated.
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● System Function Alarm [ARPA (DATA)]･･････････････････････ When an abnormal state of an input signal or a problem in the processing circuitry occurs, a character string or alarm is generated.

Since the situation is different from actual ship maneuvers, the CPA LIMIT and TCPA LIMIT should be set with ample leeway. Trial maneuvering is used to simulate the course and speed necessary to avoid a collision when a dangerous target appears.
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● Trial 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 (with the same conditions as in the True Vector mode on the previous page), it is seen that the acquired target is a dangerous one because its vector is crossing the CPA RING.
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● Using the TRIAL Function･･････････････････････････････････ Procedures 1 Press the MENU or OPTION2 key on the screen.

SECTION 6 TRUE AND FALSE ECHOES ON DISPLAY Radar Wave with the Horizon .......................................... 6-1 Strength of Reflection from the Targets ......................... 6-3 Sea Clutters....................................................................... 6-3 False Echoes..................................................................... 6-3 Display of Radar Transponder (SART) ...........................
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● 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.
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● D (nm) Height of Scanner Detective Range Height of Target Fig. 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.
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● Strength of Reflection from the Targets･････････････････････ 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.
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● [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 independent. (See Fig. 6.3) Fig. 6.3 [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.
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● [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 an abnormally long distance, at which a target may be detected by the radar.
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● 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.

This measure is taken for protecting the electronic tube emitting radar pulses. (a) Not changed to the new interconnection condition:.........................
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● The Slave Display Unit will not change the radar video even if the tuning control is adjusted because the tuning is controlled by the Master Display Unit.
