6.3 Acquiring Targets

Manual acquisition

Follow the steps below to manually acquire a target. Up to 10 targets can be manually acquired.

1.Place the cursor (+) on a target of inter- est by operating the omnipad.

2.Press the [ACQ/ENTER] key.

The plot symbol changes its shape accord- ing to the status as below. A vector appears in about one minute after acquisition indicat- ing the target's motion trend. If the target is consistently detected for three minutes, the plot symbol changes to a solid mark. If ac- quisition fails, the target symbol blinks and disappears shortly thereafter.

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 sym- bol when the target is selected for data read- ing.

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 success- ful acquisition.

Note 2: When you want to acquire 11th tar- get, cancel tracking of the one of less impor- tant targets.

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

CAUTION

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 five targets automatically by setting theAuto Acquisition area predefined in the system. If Auto ACQ is selected after more than five tar- gets have been manually acquired, only the remaining capacity of targets can be auto- matically acquired. (For example; when seven targets are acquired manually , and then the Auto ACQ is switched on only three targets can be acquired automatically.) When five targets have been automatically ac- quired, "AUT O TARGET FULL" message appears at top left corner on the display.

Setting auto acquisition area

Auto acquisition area is predefined between

2.0and 2.5 nm in range and 45 ° on either side of the heading marker in bearing. If a target come into this area, it is acquired au- tomatically.
