5.3.5 Rejecting sea clutter (Sea)
Never set the sea clutter suppression function before rejecting all the sea clutters at
close range. Detection of not only echoes from the wave and so on but also targets
such as other ships or dangerous objects may be suppressed.
When using the sea clutter suppression function
, make sure to choose the most
appropriate setting for suppression.
Memo
Remove images by sea clutter by using the sea clutter suppression function.
When using the sea 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 [Sea] (sea clutter adjustment) slider dial in Radar signal information, turn the
trackball, and adjust the amount of images by sea 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 sea clutter.
Moving the slider to the left increases the amount of images by sea clutter.
The current level of sea clutter suppression is indicated by the bar and a numeric value.
[Points on adjustments]
The sea clutter suppression function decreases the amount of images by sea clutter by lowering
reception gain at close range. When reception gain is lowered, the effectiveness of sea clutter
suppression increases; however, if excessive effect is applied, please note that targets having weak
signal strength such as buoys and small ships will disappear.
