[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. FISHING NET DETECTION
• Use this mode when searching for small targets (fishing net and fishing buoy that are hidden among
sea clutter of a near range.
• When using the fishing net detection mode to "ON", make sure to use automatic FTC or automatic
STC.
• When the fishing net detection mode is set to "ON", the sea clutter may not disappear even if the
[SEA CLUTTER] control is turn to the maximum level, as long as STC is used.
OFF : The fishing net detection mode is not used.
The preset STC is normal setting. (for vessels)
ON : The fishing net detection mode is used.
The preset STC is set to the fishing net detection mode. (for small targets)
[Page 3] 7. 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)
