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.
Radar symbology
Radar symbology defined in the Radar Settings panel can be turned on/off collectively. See
the radar panel illustration showing optional radar items.
Target trails
You can set how long the trails generated from each target on your radar panel remain. You
can also turn OFF target trails.
Ú
Note: True motion is recommended when using Target trails
Clearing target trails from the panel
When target trails are displayed on the panel, the radar menu expands to include an option
where you can clear target trails from your radar panel temporarily. The target trails start to
appear again unless you switch them off as described above.
The radar palette
Different colors (palettes) can be used to represent detail on your radar panel.
Radar orientation
Radar orientation is indicated on the upper left corner of the radar panel as either HU
(Heading UP), NU (North Up) or CU (Course up).
