4.6.2 SURFACE NOISE FILTER

An automatic filter that attempts to remove Surface Clutter that causes the screen to be
filled up with strong return echoes just below the surface. It may seem that the same
functionality could be achieved using on the STC control however there is main difference
between such control in fact the STC control impacts the capability to detect and track the
bottom and is not designed to cancel completely the surface noise, on the other side the
Surface Noise Filter attempts to cancel completely the surface noise but it doesn't affect
the capability to detect and track the bottom.
Filter gradually attenuates surface noises. The Surface Noise Filter has 9 settings: OFF, 1,
..., 8. When set to 1 the Surface Noise is attenuated from surface down to a depth of 5 Ft,
increasing the Surface Noise increases the depth in which the Surface Noise is attenuated as
well as the attenuation level increases; when the preset is set to 8 the attenuation is maximum
and is applied from surface level down to a depth of 255 Ft, as shown in the Surface Noise
Filter Table reported below:
