Radar threshold
The threshold sets required signal strength for the lowest radar signals. Radar returns below
this limit are filtered and are not displayed.
Default value: 30%.
Target expansion
Target expansion increases the length of targets in range, making them easier to see.
Rejecting radar interference
Interference could be caused by radar signals from other radar units operating in the same
frequency band.
A high setting reduces the interference from other radars.
In order not to miss weak targets, the interference rejection should be set to low when no
interference exists.
Target separation
Controls the target discrimination of the radar (separation between objects is more
prominent).
Fast scan
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
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
View menu options vary depending on your radar antenna.
VelocityTrack
Ú
Note:
When VelocityTrack is enabled antenna rotation speed may be reduced.
Ú
Note:
When operating the radar in Dual range mode with one of the ranges set to 36
nm or more, increased VelocityTrack coloring noise over land areas may be seen.
Doppler coloring is a navigation aid to distinguish moving targets approaching or diverging
from your vessel. The radar indicates if a target is approaching or diverging from your vessel
when both these conditions are true:
•
The target's relative speed is greater than the VelocityTrack speed threshold.
•
The target is not geo-stationary (e.g. land or a marker buoy).
The following options are available:
•
Off - turns off Doppler coloring
•
Normal - approaching targets and diverging targets are colored.
•
Approaching targets - only approaching targets are colored
The color of approaching and diverging targets depends on the palette used:
•
Diverging targets are blue colored on all radar image palettes.
•
Approaching target colors on radar image palettes:
- Black/Red palette - Yellow
