[RAIN] Control
When the [RAIN] control is turned clockwise, targets hidden by rain/snow clutter returns
appear on the radar display. However, be careful that excessive suppression may cause
small targets to be overlooked. Since the rain/snow clutter suppression function also has
the effect of suppressing sea clutter, the suppression efficiency improves when using
with the
[SEA] control. In general, set the value to "0".
