5. 4. 20. Noise Reduction
5. 4. 21. Noise Reduction V
The noise reduction settings are used to eliminate acoustic noise and random noise from
other ships as well as the sea clutter generated during bad sea conditions. 10 settings from
“NR1” to “NR10” are available. The standard setting is ”NR5.” While “NR1” is the weakest
signal processing,
“NR10” is the strongest signal processing. Normally the standard setting
should be used because the PP FILTER function can deteriorate the image smoothing.
The “ Noise Reduction” and “ Noise Reduction V” are used for setting the horizontal
images and the vertical images, respectively.

because this function can display stable images on the screen regardless of the pitching
and rolling of the ship.
