6.1 General

The Auto Plotter ARP-10 is an optional cir- cuit board which is accommodated in the dis- play unit of this radar (24 rpm only) radars. It requires heading data to function.

The Auto Plotter permits manual or automatic acquisition and automatic tracking of up to 10 radar targets. An internal microprocessor calculates target data such as speed and course and displays the results in alphanu- meric data and by vector. To ensure the reli- ability of the displayed target data, the radar must be properly adjusted for minimum sea returns and noise.

Principal specifications

Acquisition and tracking

Acquisition of up to 10 targets between 0.2 and 16 nm.

Automatic tracking of up to 10 acquired targets between 0.1 and 16 nm.

Vectors

 

Vector length:

30 s, 1, 3, 6, 15, 30 min.

Orientation:

True velocity or relative ve-

 

locity

Past positions:

5 past positions at intervals

 

of 15, 30 s, 1, 2, 3, 6 min.

Alarm:

Visual and audible alarms

 

against targets violating CPA/

 

TCPA limits, Visual alarm

 

against lost targets

Target discrimination: A target measuring about 800 m or more in the radial or circum- ferential direction is regarded as a landmass and not acquired or tracked. Echoes smaller than about 800 m are regarded as true tar- gets.

Keys used for auto plotter

The ARP-10 uses the following touchpad keys. Given below is a brief description of these keys.

MENU: opens/closes the main menu.

SELECT/CANCEL:

A long press terminates plotting of the target selected with the cursor , and a brief press displays the data of the target selected with the cursor.

ACQ/ENTER: Acquires the target selected with the cursor.

6.2 ARP-10 MENU Operation

The ARP-10 MENU contains the following items.

Display: Turns on/off the plot symbols, past positions and target data.

All Cancel: Cancels the tracking of all targets.

Vector Ref: Selects relative or true vectors. To select your choice, open the ARP-10 menu. Select “3 V ector Ref” to Relative or Ture, and then, press the [ACQ/ENTER] key.

Vector Length: Selects vector time.

History: Selects past position plot interval.

CPA Set: Selects CP A alarm limit. When a target is predicted to come within this limit, an audible alarm sounds and at the same time the corresponding target symbol changes to a blinking triangle.

Note: If the preset CPA limit is set at OFF, a target which is on collision course will not produce an alarm.

TCPA Set: Selects TCPA alarm limit.

Auto ACQ: Turns on/off Auto Acquisition Area.

Activating the auto plotter

To activate the Auto Plotter, follow the steps shown below.

1.Adjust the GAIN, A/C SEA and A/C RAIN controls for proper radar picture.

2.Press the [MENU] key to open the main menu.
