If untracked targets intrude into the guard zone in the
conditions that maximum number of targets is under
tracking, the targets acquired automatically will be
cancelled in the order of lower levels of danger.
5.2 ATA OPERATION
This section explains how to use the ATA functions.
Each function is available only when the ATA option is installed.
The functions automatically track a target, and store/display vectors as the course and speed.
They calculate CPA and TCPA, and issue an alarm.
The ATA function can track up to 30 ships.
The guard zones can be set for automatic acquisition.
When the power is turned off or the transmit/standby mode is activated, tracking data is erased from memory.
