20.15 Radar sensitivity controls
Optimum performance is usually achieved using the default settings. You
can adjust the image using the Sensitivity controls to improve the displayed
image.
Sensitivity settings can be accessed using the onscreen
[Image adjustment] icon, or the Adjust sensitivity menu
option: [Menu > Adjust sensitivity] .
The Sensitivity controls available are dependant upon the Radar scanner in
use.
Control Name Description
[‘G’ Gain] The control determines the signal
strength at which target returns are
shown onscreen.
The Gain control can be set to
[Auto] or
[Manual] .
A higher value produces more target
returns and noise onscreen.
[‘R’ Rain] Precipitation appears on the Radar
screen as lots of small echoes which
continuously change size, intensity and
position. The Rain control suppresses
these echoes making it easier to identify
real object.
The higher the Rain control is set the
more echoes will be suppressed.
[‘S’ Sea] Radar echoes from waves can clutter
the Radar screen. The Sea control
suppresses these echoes (for up to 5
nm depending on conditions) making it
easier to identify real objects.
The higher the Sea control is set the
more echoes will be suppressed.
[‘CG’ Color Gain] The control sets the lower limit for the
color used for the strongest target
returns. All target returns above this
value are displayed in the strongest
color. Those with a weaker value are
divided equally between the remaining
colors.
The control can be set to
[Auto] or
[Manual] .
[All to Auto] Sets all Sensitivity settings to [Auto] with
0% offset.
