Sea Clutter suppression level 

 

    Sea Clutter suppression level 

LOW 

 

 

 

 

Suitable level 

 

 

 

 

 

 

 

 

 

 

 

 

 

When using the sea clutter suppression function, never set the suppression 

level too high canceling out all image noises from the sea surface at close 

range. Detection of not only echoes from waves but also targets such as 

other ships or dangerous objects will become inhibited. When using the sea 

clutter suppression function, make sure to choose the most appropriate 

image noise suppression level.

 

The sea 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. 

It is necessary to adjust the sea clutter suppression level in order to use 

the radar exactly. Failure to do so, it is possible to obtain an accurate 

radar echo. 

How to change the SEA clutter suppression level

: Please refer to the sea clutter suppression adjustment 

method described in Chapter 2.4.3.
