Advanced radar options
Radar threshold
The threshold sets required signal strength for the lowest radar signals. Radar returns below
this limit will be filtered and not displayed.
Default value: 30%.
Target boost
The target boost option is used for increasing the size of radar targets.
Target expansion
Target expansion will override and increase the default radar pulse length, providing larger
target returns.
Fast scan
(Broadband Radar™ only).
Increases the speed of the radar scanner when the range is set to 2 nm or less. This option
gives faster updates on target movements within this range.
STC curve
(Broadband Radar™ only).
The STC (Sensitivity Time Control) controls the sensitivity of the radar signal close to your
vessel. It compensates for distance to the radar object, making returns from equal sized
objects appear with the same size on the radar image.
Radar view options
Radar symbology
Radar symbology defined in the 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 will be expanded to include an
option where you can clear target trails from your radar panel temporarily. The target trails
will 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.
