6.7.2 Alarm for new target acquired in automatic
acquisition guard zone (New target)
In setting an automatic acquisition guard zone, it is necessary to adjust the gain, sea
clutter suppression and rain/snow clutter suppression to ensure that target echoes
are displayed in the optimum conditions.
No automatic acquisition guard zone alarms will be issued for targets undetected by
the radar, and this may cause accidents such as collisions.
The automatic acquisition function sets a zone in a range and issues an alarm when a new target
(which is not yet acquired) goes into this zone.
For the setting of an automatic acquisition guard zone, refer to "6.5.1 Acquiring target".
