Automatic Acquisition Zone
Guard
Two automatic acquisition zones may be set in a sector or
Zone
any form. They also act as suppression zones, avoiding
unnecessary overloading to the processor and clutter by
disabling automatic acquisition and tracking outside them.
Targets in a automatic acquisition zone appear as inverse
triangle. The operator can manually acquire important targets
without restriction.
CPA Alarm Zone
Target tracking symbol changes to a triangle when its
predicted course (vector) violates the operator set
CPA/TCPA. The operator can readily change the vector
lengths to evaluate target movement trend.
Guard Zones and Anchor Watch Zone
Guard Zones generate visual and audible alarms when
targets enter the operator set zones. One of Guard Zones
may be used as an anchor watch to alert the operator when
own ship or targets drift away from the set zone.
The target trails feature generates monotone or gradual shading
afterglow on all objects on the display. The shading afterglow
paints the display just like on an analog PPI. The monotone
trails are useful to show own ship movement and other ship
tracks in a specific fishing operation. The trail time is adjustable
for 15, 30 s, 1, 3, 6, 15, 30 min or continuous. The target trails
are indicated in a different color from background. The unique
feature in this radar is a choice of True or Relative mode in
Relative Motion (only True in TM).
Up to 200 waypoints and up to 30 routes can be stored.
Each route may contain up to 30 waypoints. A radar map is
a combination of map lines and marks whereby the user can
define and input the navigation area, route planning and
monitoring data. The radar map has the capacity of 3,000
points for map lines and marks. The map data can be
memorized to facilitate repeated use on a routine navigation
area.
