3.8.1.2 Video Noise Rejection
• This function rejects signals that assumed as noise and clutter in radar videos.
• Select to display radar videos like analog signals.
• Select or to suppress noise and clutter.
3.8.1.3 Auto Dynamic Range
• When the automatic sea clutter suppression mode and the automatic rain/snow
clutter suppression mode are in use, the dynamic range is automatically
controlled.
• When the automatic sea clutter suppression mode is in use, this function
improves gain by widening the dynamic range of only areas where sea clutter
is strong and narrowing the dynamic range of areas where sea clutter is not
detected.
• When the automatic rain/snow clutter suppression mode is in use, this function
improves gain by widening the dynamic range of areas where sea clutter and
rain/snow clutter are strong and narrowing the dynamic range of the other
areas.
• Land videos become obscure when the automatic rain/snow clutter suppression
mode is in use.
：
Turns off the noise rejection function, and displays all
signals. Targets are popped up from noise and displayed
like analog signals.
：
Rejects the signals of definitely unwanted waves (noise and
clutter). When detection of targets or unwanted waves is not
definite, the signals are displayed.
：
Rejects the signals of definitely unwanted waves (noise and
clutter). When detection of targets or unwanted waves is not
definite, the signals are rejected. Only when detection of
targets is definite, the signals are displayed.
：
Does not control the dynamic range automatically.
(Standard setting) The dynamic range is set in the same
manner as when the manual sea clutter suppression mode
or the manual rain/snow clutter suppression mode is in use.
：
Automatically controls the dynamic range.
