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 2.4.3.
