[Page 3] 5. SMALL BUOY DETECTION
• In this mode, the signal processing circuit loss is low when small buoy are detected.
OFF : Normal signal processing setting.
ON : The radar interference processing circuit is switched to small buoy detection
processing.
Low loss IR processing ➝ IR1 of small buoy detection
Normal IR1 ➝ IR2 of small buoy detection
Normal IR2 ➝ IR3 of small buoy detection
However, the interference elimination performance of low loss IR processing
is lower than that of normal IR processing.
[Page 3] 6. AUTOMATIC DR CONTROL (AUTO DR CONT)
• Automatically controls "VIDEO LATITUDE" (dynamic range) when automatic STC or FTC is used.
• At automatic STC, this mode expands the dynamic range only for the area with strong sea clutter and
reduces the dynamic range for the area without sea clutter, enhancing the sensitivity.
• At automatic FTC, the mode expands the dynamic range of the area with strong sea clutter and rain/
snow clutter and reduces the dynamic range of other areas, enhancing the sensitivity.
• When automatic FTC is used, land images become weak.
OFF : DR (dynamic range) automatic control is not performed.
The dynamic range (video latitude) is the same setting as that of manual STC.
ON : Performs automatic DR control. (normal setting)
