Effects of transmitter pulse length
With SP selected:
The transmitter pulse 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
With MP selected:
The normal transmitter pulse length is set.
Both range resolution and gain are appropriately set.
Recommended condition for selection:
General navigation
With LP selected:
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.
Recommended condition for selection:
Detection of small targets in good weather conditions
Usable transmitter pulse length differs according to the type of scanner unit being used and the
observation range being used. For usable pulse length, see Section 11 “SPECIFICATIONS”.
