[Page 1] [5] Auto STC / FTC (Auto Sea / Rain)
• Detects unwanted waves such as rain / snow clutter and sea clutter and automatically suppresses
them.
• When the sea state or weather changes, this function automatically performs suppression
processing in accordance with the situation.
• Suppression processing is not full automatic, and requires the operator to adjust the afterimages of
unwanted waves.
• To adjust the afterimage of sea clutter, use the [SEA] dial.
• To adjust the afterimage of rain / snow clutter, use the [RAIN] dial.
• In areas where the density of unwanted waves is low, unwanted waves may remain being judged
as targets. Thus, use the automatic clutter suppression mode together with the video process
mode.
• Characteristics of the automatic clutter suppression function.

[Page 3] [1] - [7] Process Setting
•
Operation is the same as that of the Process Setting menu described in Section 3.8.1.
: Disables the automatic clutter suppression function.
Select off when rain / snow clutter and sea clutter are not strong
or when the ship is in a bay.
: Automatically detects the strength of sea clutter, and performs the
most suitable sea clutter suppression processing.
Even when the strength of sea clutter varies depending on the
wind direction, AUTO Sea performs the most suitable suppression
processing.
Land like islands can be displayed naturally.
Since rain clouds outside sea clutter areas are recognized as land,
there is no effect of suppressing rain / snow clutter.
: Along with AUTO Sea, AUTO Rain automatically detects the
strength of rain / snow clutter, and performs the most suitable rain
/ snow clutter suppression processing.
When rain clouds are scattered about, AUTO Rain performs rain
/ snow clutter suppression processing for only the rain-cloud areas.
Since land is recognized as rain clouds, land videos become
obscure.
