Set the FTC Curve. User selects the "river" or "sea" of the curve selection. Please do not change the FTC
offset and slope correction. If the value changed, affects rain clutter suppression function drastically.
When using the rain 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.
