2.6 Removing Sea Clutters
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.
Using the function of automatic sea clutter suppression mode
The sea clutter suppression in accordance with the intensity of sea clutter is possible. Use this mode
when the sea clutter's intensity differs according to directional orientation.
