Anti-clutter rain
Rain/snow clutter suppression.
Anti-clutter sea
Sea clutter suppression.
AZI
AZImuth stabilization mode
B
BCR/BCT
Bow Crossing Range and Bow Crossing Time
C
C up
Course up
Own ship’s course is pointed to the top center of the radar display.
CCRP
The Consistent Common Reference Point
A location on own ship, to which all horizontal measurements such as target range,
bearing, relative course, relative speed, CPA or TCPA are referenced, typically the
conning position of the bridge.
Clutter
Unwanted reflections on a radar screen, from sea surface, rain or snow.
COG
Course Over Ground
The direction of the ship's movement relative to the earth, measured on board the ship,
expressed in angular units from true north
CORREL
Correlation
CPA/TCPA
The distance to the Closest Point of Approach and Time to the Closest Point of
Approach. Limits are set by the operator and are related to own ship.
CTW
Course Through Water
