[Page 1] [3] Process (video process)
･ Same function as PROCESS Setting described in Section “3.4.4 Use Video Processing”.
[Page 1] [4] Target Enhance
Same function as TARGET ENHANCE Setting described in Section “3.4.3 Target
Enhance”.
[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:
Off : 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.
AUTO Sea : 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.
AUTO Sea/Rain : 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.
[Page 2] [1]-[5] PL (Pulse Width)
･ Sets the standard transmitter pulse length in each range.
･ When the range is called, the pulse range is used.
[Page 3] [1]-[7] Video setting menu (Process Setting)
･ Operation is the same as that of the Process Setting menu described in Section “3.8.1 Set Radar Signal
Processing”.
[Page 4] [1]-[6] Radar trails settings (Trails Setting)
･ Same functions as in the Trails Setting of the RADAR Menu described in Section “3.8.2 Set Radar
Trails”.
