Moving the slider to the right decreases the amount of images by rain/snow clutter.
Moving the slider to the left increases the amount of images by rain/snow clutter.
The current level of rain/snow clutter suppression is indicated by the bar and a numeric value.
[Points on adjustments]
When the amount of images by rain/snow clutter is decreased, the outlines of targets hidden by images
of rain/snow will appear, but please note that small targets may be missed. Since this can also reduce
sea clutter, it is effective to use it together with the sea clutter rejection function.
Normally, set the level of rain/snow clutter suppression to 0.
Memo
If the optimal setting value was lost, it is recommended to reset to
the initial value and tune up again.
The initial setting value is indicated as shown in the figure at right.
Using the automatic rain/snow clutter suppression mode
The rain/snow clutter suppression in accordance with the intensity of rain/snow clutter is possible. Use
this mode when the rain/snow clutter's intensity differs according to directional orientation.
1 Click on the Automatic Rain/Snow Clutter Suppression button.
[AUTO] (automatic) is displayed on the automatic rain/snow clutter suppression
button.
Each time this button is clicked on, the display switches between [AUTO] (automatic) and
[MAN] (manual).
2 Click the left mouse button of the button on the [Rain] (rain/snow clutter adjustment)
slider, drag it with the trackball, and adjust the volume of the echo created by
rain/snow clutter that is displayed on the screen.
Even while auto rain/snow clutter is being suppressed, the amount of images can be
fine-adjusted manually.
