Acquisition zone
D The ACQUISITION ZONE is used for automatic target acquisition and
subsequent target tracking.
If a ship enters the ACQUISITION ZONE the radar outputs a “Guard Zone Alarm”.
The target is automatically acquired and tracked.
NOTE
The ACQUISITION ZONE is considered to be an essential aid and
information source for assessing the situation.
The decision as to whether a shortrange situation will develop from this
information must be made by the navigator himself!
Guard zone
D If an acquired target enters this GUARD ZONE, the radar outputs a “Guard
Zone Alarm” but the target is not acquired and tracked.
NOTE
The GUARD ZONE and related target acquisition are only intended to
draw the radar observer’s attention to a target.
The decision as to whether a shortrange situation will develop from this
information must be made by the navigator himself!
Exclusion zone
D If the user wants to exclude certain areas from automatic acquisition, he can
create an EXCLUSION ZONE. In this zone, all possible targets will be
ignored.
NOTE
Within the exclusion zone, no targets are acquired and displayed in the
radar video.
The master and navigator are responsible for assessing and considering
any possible collision situations that could result from this.
