where many boats and ships are running. (Importance is attached to resolution.)
Open-sea
Open-sea navigation
Use this scene to monitor a relatively long range, for example, the open-sea.
(Importance is attached to long range gain)
Fishnet

Use this scene to detect small targets such as fishnets of round haul netters hidden
by sea clutter returns. (Importance is attached to sea clutter suppression, and gain to
moving targets lowers.)
Storm
Storm
Use this scene when many rain/snow clutters or sea clutter are detected in stormy
weather. (Importance is attached to rain/snow clutter and sea clutter suppression,
and gain slightly lowers.)
Calm

Use this scene when only a few rain/snow clutter or sea clutter are detected.
Rain
Rain
Use this scene when sea clutter is not strong but rain/snow clutter is strong.
