Example
The transmitter pulse becomes shorter, and the range resolution improves.
The effect of suppressing sea clutter returns and rain / snow clutter returns heightens.
In bays / harbors where targets are densely crowded
Rough sea state due to torrential rain or stormy weather
The normal transmitter pulse length is set.
Both range resolution and gain are appropriately set.
General navigation
The transmitter pulse becomes longer, and gain improves.
Small targets are zoomed and are easy to observe.
When the sea state is bad, detection performance decreases.
