5.3.6 Rejecting rain/snow clutter
Never set the rain/snow clutter suppression function too high.
Detection of not only echoes from the rain or snow but also images targets such as
other ships or dangerous objects may be suppressed.
When using the rain/snow clutter suppression function
, make sure to choose the
most appropriate setting for suppression.
Memo
Remove images by rain/snow clutter by using the sea clutter suppression function.
When using the rain/snow clutter suppression function, make the optimum setting giving
considerating to the setting described in "5.3.7 Adjusting
to optimal images (Selection of
observation scenes)".
1 Drag the [Rain] rain/snow clutter adjustment slider dial in Radar signal information,
turn the trackball, and adjust the amount of images by rain/snow clutter displayed on
the screen so as to make display easy to observe.
Moving the slider to the right decreases the amount of images by rain/snow clutter.
Moving the slider to the left increases the amount of images by rain/snow clutter.
The current level of rain/snow clutter suppression is indicated by the bar and a numeric value.
[Points on adjustments]
When the amount of images by rain/snow clutter is decreased, the outlines of targets hidden by images
of rain/snow will appear, but please note that small targets may be missed. Since this can also reduce
sea clutter, it is effective to use it together with the sea clutter rejection function.
Normally, set the level of rain/snow clutter suppression to 0.
