Effects of transmitter pulse length
SP :
The transmitter pulse length becomes shorter, and the range resolution improves.
The effect of suppressing sea clutter returns and rain/snow clutter returns heightens.
Recommended condition for selection:
In bays / harbors where targets are densely crowded
Rough sea state due to torrential rain or stormy weather
MP :
The normal transmitter pulse length is set.
Both range resolution and sensitivity are appropriately set.
Recommended condition for selection:
General navigation
LP :
The transmitter pulse length becomes longer, and sensitivity improves.
Small targets are zoomed and are easy to observe.
When the sea state is bad, detection performance decreases.
Recommended condition for selection:
Detection of small targets in good weather conditions
Usable transmitter pulse length varies according to the type of scanner unit being used
and the observation range being used. For usable pulse length, see the section
