5.16.6 VIDEO NOISE REJECTION
This function rejects signals that assumed as noise and clutter in radar videos.
OFF: Turn off the noise rejection function, and display all signals. Targets are popped up from noise and
displayed like analog signals.
Level1: Reject the signals of definitely unwanted waves (noise and clutter). When detection of targets or
unwanted waves in no definite, signals are displayed. When detection of targets is definite, signals
are displayed.
Level2: Reject signals of definitely unwanted waves (noise and clutter). When detection of targets or
unwanted waves in no definite, the signals are displayed. When detection of targets is definite, the
signals are displayed. It will remove the signal that can be regarded as unnecessary wave of more
than level 1.
Level3: Select if “Level1” and “Level2” cannot reject signals enough.
5.16.7 VIDEO LATITUDE
Select the dynamic range in which receiving signals are to be shown on the radar display.
Narrow: Narrow the dynamic range at short range.
Normal: Standard setting. The dynamic range varies depending on the actual range.
Wide1: Use this mode when rainy weather intensifies unwanted waves. The dynamic range is about
twice as wide as when Normal is selected.
Wide2: Use this mode when rain clouds remain even when using Wide1.
Max: Use this mode when you want to fine-tune the image for weak reflectors such as rain clouds.
Dynamic range is 2.5 ~ 5 times as large as normal.
Select Normal in standard, and Wide1 in rainy weather. Narrow clearly displays short-range videos when STC
is used in manual mode.
