[Page 3] 1. VIDEO LATITUDE
• Select the gradation for displaying received signals on a screen.
• Use "NORMAL" as the standard condition and select "WIDE" in rainy weather.
• In "NARROW" mode, images of a close range are displayed in strong contrast.
NORMAL : Setting in the standard use.
The display dynamic range varies according to the range.
Short range setting > medium range setting > long range setting
WIDE : Setting when the radar is used in rainy weather.
The range is approximately doubled from that of "NARROW" in each range.
NARROW : Obtains images of strong contrast by narrowing the dynamic range of a near range.
[Page 3] 2. VIDEO NOISE REJECTION
• Eliminates signals that are assumed to be noise and clutter from radar videos.
• Select "OFF" when displaying radar videos in analog mode.
• Select "LEVEL1" or "LEVEL2" when suppressing display of noise and clutter.
• Select "LEVEL1" or "LEVEL2" when using "BLUE" as the background color.
OFF : Sets noise elimination to Off and displays all the signal levels.
Displays images in analog signal mode by floating echoes in the noise.
LEVEL 1 : Completely eliminates signals that are assumed to be undesired clutter (noise, rain/
snow).
Displays signals that cannot be definitely defined to be signals or undesired clutter.
LEVEL 2 : Completely eliminates signals (noise and clutter) that are assumed to be undesired
clutter (noise, rain/snow).
Eliminates signals that cannot be definitely defined to be signals or undesired clutter.
Displays signals that can be definitely defined as signals.
