Region Description

The highest priority. The target will be tracked preferentially when it
enters the alarm area.
When targets appear both in the alarm area and pre-warning area,
only the target in alarm area will be tracked.
Pre-warning area and shield area are subject to alarm area, when
three areas overlap.
Pre-warning
area
Secondary priority. The target will be tracked when it enters the
pre-warning area.
Shield area is subject to pre-warning area, when they overlap.
Shield area
The target will not be tracked, and its trace will not be displayed in
the shield area.
When there are areas with objects that might cause misinformation
such as trees in radar's detection area, but not in alarm or
pre-warning areas, you can set them as shield area.
