INSTRUCTION MANUAL
2.6 RAIN/SNOW CLUTTER SUPPRESSION
This function suppresses rain/snow clutter returns.
CAUTION
When using the sea 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 sea clutter suppression function, make sure to
choose the most appropriate image noise suppression level.
