12 to 18NM PM Pattern

2 Checking Transmitter System
The value of the TRANSMIT POWER indicator bar graph in the test menu indicates the value corresponding to the transmission output power. 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

Read a current value A on the bar indicator. 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. Then, obtain a relative attenuation d (A) for the value A referring to the Calibration Curve I. The value given by d (A) - d (B) represents the attenuation of the current transmission output power compared with the value at the initial time. If the attenuation value given by d (A) - d (B) is 10 dB or more (due to the life of the magnetron), it is necessary to request for checking of the transmitter system by a service engineer.

Calibration Curve I

Initial bar length Relative Attenuation d Date and time of initial setting Maximum range pattern

Measurement precision

Length of Bar Indicator l Figure 1
(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.

Execute manual target acquisition in the automatic acquisition mode, that is, in the state in which the Automatic Acquisition mode [GZ1, GZ2] is ON. Use of Combined Auto/Manual Mode When both automatic and manual acquisition modes are used concurrently, important targets should be acquired manually, and the rest should be acquired automatically. If new targets enter the zone and they exceed the maximum number of targets that can be acquired, manual targets will continue to be displayed until they leave the guard zone, but automatically acquired targets will be cancelled according to their degree of importance.

ARPA DATA DISPLAY

(Refer to the Display Example on page 2-1.)

Display of Vectors

When a targeting or the own ship changes course or when a target is acquired, the vector may not reach a given level of accuracy until three minutes or more has passed after such a course change or target acquisition. Even if three minutes or more have passed, the vector may include an error depending upon the tracking conditions.
A vector representing a targets predicted position can be presented in the TRUE vector or RELATIVE vector mode. minutes. In each mode, a vector length can be freely changed for a time interval of 1 to 60

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, the own ships vector is displayed as shown below. In this mode, the movements of other ships around own ship can be accurately and easily monitored. However, no CPA RING can be displayed in this mode.

Own ships vector

The relative vector is not displayed. True vector
Relative Vector Mode In order to display the relative vector of a target, press the T/R VECT switch to select the Relative Vector mode. The relative vector does not represent the true motion of a target, but its relative relation with the own ship. This means that a target with its relative vector directed at the own ship (passing through the CPA LIMIT ring) is a dangerous target. In the Relative Vector mode, the CPA LIMIT of targets can be seen at a glance.
CPA RING Relative vector The true vector is not displayed.
Therefore, the TRUE/REL modes can be used in the following way: The TRUE vector can be used to know the true aspect of a target, and the REL vector can be used to know the closest point of approach (CPA) of a target.

Move the cross cursor to a target (being target) to indicate its data using the trackball. Next, press the right trackball button to select it.
The data of the designated target will be deleted, and the symbol will, change to acquisition mark.

ALARM DISPLAY

The ARPA system provides the following alarms: Dangerous target alarm: CPA/TCPA Guard zone intrusion alarm: GZ Lost target alarm: LOST System function alarm: ARPA (DATA) Gyro set alarm: SET GYRO
Dangerous Target Alarm: (CPA/TCPA)
If either the CPA LIMIT or TCPA LIMIT is set to zero, then the dangerous target alarm will not operate. 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.
In the ARPA system, targets are categorized into two types: tracked targets and dangerous targets. The degree of danger can easily be recognized on the display at a glance, so that an officer can easily decide to which target he should pay attention. The types of targets and alarms are shown below. Dangerous Target Alarm Status Tracking target Dangerous target Symbol on CRT Alarm characters (OFF) CPA/ TCPA Alarm sound Conditions CPA>CPA LIMIT 0>TCPA TCPA>TCPA LIMIT CPACPA LIMIT 0TCPATCPA LIMIT

Guard Zone Alarm [GUARD ZONE]
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.
The guard zone function is used to set a zone at an arbitrary range and to sound an alarm if a target intrudes into this zone. Refer to section 3.4 Set Guard Zones on how to set guard zones.

Guard zone

Guard Zone Alarm
Status Target entering the guard zone Symbol on CRT Alarm characters Alarm sound Beeping (pipipi) Acknowledgeable GZ Conditions An alarm sound is generated when a target enters the 0.5 NM range between the outer and inner rings.
Lost Target Alarm [LOST TARGET]
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. The typical causes for this alarm are shown below, but they are not limited to these: The target echo is very weak; The target has entered the shadow of land or a large ship and its echo is not being received; The target echo is hidden by sea clutter.

Gate Size

Do not change the preset gate size carelessly. If the gate value is improper, the ARPA acquisition and tracking functions may deteriorate. Otherwise, this may cause accidents to occur.
The Gate Size is defined as an Area Within which targets are watched by the ARPA processing circuit. If the gate size is too large, targets are not lost but may be swapped with other close targets. If the gate size is too small, targets are not easily swapped, but may be lost. The ARPA processing circuit is designed to detect target sizes and set an accurate gate size depending on the ranges and sizes of those targets (NARROW is the standard size). However, change the setting parameters to select the best size in the following conditions:
Set 2.NARROW in normal operation.
