A 0° 5432 1 B 0° 1 2 3 4 5 C D The examples show the target movement (1-5) over 5 radar scans with the radar in relative motion mode. In example C, own vessel COG is 0°, and speed is 0 knots. In example D, own vessel COG is 0°, and speed is 10 knots. In both examples, the target COG is 270°, and the speed is 20 knots. The colors in the examples are according to the colors used for black/green and black/yellow radar palettes: • Red (C1/C2 and D1/D2), indicating the target is on an approaching path to own vessel. Its relative speed at that point is greater than the VelocityTrack speed threshold. • Not colored (C3 and D3/D4), indicating it is temporarily neutral because its relative speed at that point is less than the VelocityTrack speed threshold. • Blue (C4/C5 and D5), indicating the target is diverging away from own vessel and its relative speed at that point is greater than the VelocityTrack speed threshold.

The examples show the target movement (1-5) over 5 radar scans
with the radar in relative motion mode.
In example
C
, own vessel COG is 0°, and speed is 0 knots.
In example
D
, own vessel COG is 0°, and speed is 10 knots.
In both examples, the target COG is 270°, and the speed is 20 knots.
The colors in the examples are according to the colors used for
black/green and black/yellow radar palettes:
•
Red (
C1
/
C2
and
D1
/
D2
), indicating the target is on an
approaching path to own vessel. Its relative speed at that point is
greater than the VelocityTrack speed threshold.
•
Not colored (
C3
and
D3/D4
), indicating it is temporarily neutral
because its relative speed at that point is less than the
VelocityTrack speed threshold.
•
Blue (
C4
/
C5
and
D5
), indicating the target is diverging away
from own vessel and its relative speed at that point is greater
than the VelocityTrack speed threshold.
