3.5.3 When the sea is rough [AUTO-SEA]
Do not set the sea clutter suppression function to a level at which it clears all sea
clutters in short range.
Otherwise, not only echoes from waves but also the targets of ships or dangerous
objects are suppressed, which may disturb the detection.
Set the best suppression level whenever you use the sea clutter suppression
function.
If the sea becomes rough, echoes (sea clutters) from waves are displayed on the PPI screen. As a
result, the images of echoes from ships or the likes are difficult to view. Sea clutters appear more
clearly in shorter ranges.
Use of the manual or automatic sea clutter function suppresses sea clutters and makes it easy to
observe targets.
While the automatic sea clutter function is working, the manual rain/snow clutter function
(control) cannot be used.
To select the manual or automatic rain/snow clutter function of this radar, operate the
[AUTO-SEA]
control. When the automatic sea clutter suppression function is ON, "A SEA" is
displayed on the upper right of the screen.
(a) Switching the sea clutter suppression mode
If manual sea clutter suppression is currently selected, pressing the
[AUTO-SEA]
control key
changes to automatic sea clutter suppression. If auto sea clutter suppression is currently
selected, pressing the
[AUTO-SEA]
control key changes to manual sea clutter suppression.
The automatic sea clutter suppression mode
and
manual sea clutter suppression mode
are switched back and forth each time the key is pressed.
(b) Turning the sea clutter control
If manual sea clutter suppression is currently selected, as the sea clutter control is turned
clockwise, the sea clutter suppression function works more strongly.
