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
