The best image capture is needed to understand the feature of the setting for the radar signal processing
and to adjust appropriately to each oceanic condition. If overall setting is adjusted by manual operation,
even skillful person may be difficult to adjust perfectly it.
The function mode (FUNC) of the signal processing has set to apply general usage environmental

in many cases the best image is gotten quickly.
To get the best image should be set appropriately the function mode.

etc. (Valued resolution)
Deep Sea: Apply to observe relatively long ranges, open ocean, etc. (Valued long range
sensitivity)
Storm: Apply to heavy sea / rain-snow clutter. (Valued sea / rain-snow clutter, somewhat
deteriorated sensitivity)
Rain: Apply to heavy rain-snow clutter, while sea clutter is not so heavy. (Valued
rain-snow clutter, somewhat deteriorated sensitivity)
