Acquiring targets

Manual Acquisition

Follow the steps below to manually acquire a target. Up to 10 targets can be manually ac- quired.

1.Place the cursor (+) on a target of interest by operating the omnipad.

2.Press the [ACQ/ENTER] key.

The plot symbol changes its shape according to the status as below. A vector appears in about one minute after acquisition indicating the target's motion trend. If the target is con- sistently detected for three minutes, the plot symbol changes to a solid mark. If acquisi- tion fails, the target symbol blinks and disap- pears shortly.

SQUARE (dotted)

Immediately after acquisition - Plot symbol shown in broken lines.

SQUARE (dotted with a vector)

One minute after acquisition - Vector still un- reliable.

CIRCLE (Solid with a vector)

3 minutes after acquisition - Plot symbol changes to a solid circle indicating the stable tracking condition.

LARGE CIRCLE

The plot symbol of a target under tracking becomes twice as large as the normal symbol when the target is selected for data reading.

Note 1:The target to be acquired should be within 0.2 to 16 nm from own ship and not obscured by sea or rain clutter for successful acquisition.

Note 2:When you want to acquire 11th target, cancel tracking one of less important targets.

Note 3:When auto acquisition mode (Auto ACQ) is on, up to 5 targets can be acquired. For detail, see next section titled Automatic Acquisition.

WARNING

When a tracked target nears another tracked target, the targets may be "swapped." When two targets come close to each other, one of the two can become a "lost target." Should this happen, reacquisition of the "lost target" is required after the two targets have separated.

Automatic Acquisition

The Auto plotter ARP-10 can acquire up to 5 targets automatically by setting the Auto Ac- quisition area predefined in the system. If Auto ACQ is selected after more than 5 targets have been manually acquired, only the remaining capacity of targets can be automatically ac- quired. Example; when 7 targets acquired manually, then the Auto ACQ is switched on only 3 targets can be acquire automatically. When five targets have been automatically acquired, "AUTO TARGET FULL" message appears at top left corner on the display.
