Chapter 3 ADJUST THE RADAR ECHO
3.4 RAIN/SNOW CLUTTER SUPPRESSION
Rain clutter suppression level suitable Rain clutter suppression level excessive
(fine weather) (some targets become small)
The [RAIN] control can make targets hidden by rain/snow clutter returns appear on the radar display.
Be careful that excessive suppression may cause small targets to be overlooked.
When using the rain/snow clutter suppression function, never set the
suppression level too high canceling out all image noises from the rain or
snow at close range. Detection of not only echoes from the rain or snow but
also targets such as other ships or dangerous objects will become
inhibited. When using the rain/snow clutter suppression function, make
sure to choose the most appropriate image noise suppression level.
It is necessary to adjust the rain/snow clutter suppression level in order to use
the radar exactly. Failure to do so, it is impossible to obtain an accurate radar
echo.
The rain/snow clutter
suppression level is
displayed in the bottom
portion of the icon. It is
possible to judge the
suppression level by the
length of a green bar
roughly.
How to change the RAIN clutter suppression level : Please refer to the rain clutter suppression adjustment
method described in Chapter 2.3.3.
