6.4 How to Reduce the Sea Clutter
The reflected echoes from waves appear at the central part
of the screen and have the name "sea clutter". The sea clut-
ter increases in width as the height of waves and the height
of the antenna above the water increase. If the sea clutter is
strong, targets can be hidden inside the clutter, like in the
right-hand figure.
When the sea clutter hides targets, adjust the sea control
(automatically or manually) to reduce the clutter. Like with
gain, sea clutter can be adjusted from the pop-up menu or
data area. See the procedures in section 6.3.
For automatic sea clutter suppression, there are two meth-
ods: [Advanced] and [Coastal]. [Advanced] provides for
standard suppression of sea clutter and is intended for nor-
mal use. [Coastal] suppresses sea clutter further than does
[Advanced] and paints land and target echoes thicker. Use
[Coastal] when you are cruising along a coastline. To select an automatic sea clutter
suppression method, open the pop-up menu, tap [Auto Sea Mode] then turn on [Ad-
vanced] or [Coastal].
