Fast scan
(Broadband and Halo radar only).
Sets the speed of the radar antenna rotation. This option gives faster target updates.
Ú
Note: Maximum speed may not be achieved depending on the radar Settings, Mode,
and Range selected. The radar will only rotate as fast as the current control settings allow.
Sea State
Set the Sea State control according to current sea conditions for best sea clutter rejection.
Target boost
(3G and 4G Broadband, and Pulse Radar only)
The target boost control increases pulse length or reduces radar bandwidth to make targets
appear larger in range and increase radar sensitivity.
Radar view options
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).
Heading up
Rotates the radar image to display the current heading directly up on the radar image.
North up
Rotates the radar image with the north direction upwards.
Course up
Rotates the radar image to display the current navigation course directly up.
This option works only when the system is navigating an active route. If you are not
navigating an active route, the heading up orientation is used until the navigation function is
started.
Positioning the radar center
You can move the radar PPI (Plan Position Indicator) center to different positions within the
radar panel, and select how your vessel symbol moves on the radar image.
Radar motion is indicated on the upper left corner of the radar panel as either TM (True
motion) or RM (Relative motion).
The radar position can only be changed when the radar is transmitting.
