5.16.1 PULSE WIDTH
You can change the transmission pulse width. Options of the transmitter pulse width vary depending on the
range. For details, see following list.

SP(Short Pulse): The transmission pulse width becomes shorter, and the range resolution improved.
The suppression of sea clutter or rain/snow clutter is heightened.
Recommended conditions are following.
࣭
In bays/harbors and narrow waterway where targets are densely crowed.
࣭
Rough sea state due to torrential rain or stormy weather.
MP(Middle Pulse): The normal transmission pulse width is set. Both range resolution and sensitivity are
appropriately set. Recommended conditions are General navigation.
LP(Long Pulse): The transmission pulse width becomes longer, and sensitivity improved.
Small targets are zoomed and are easy to observe. When the sea state is bad, detection
performance decreases. Recommended conditions are following.
࣭
Detection of small targets in good weather conditions, at long range.
5.16.2 IR (INTERFERENCE REJECTION)
You can eliminate the interference from other radars by setting an appropriate IR level. However, if a higher
IR level is selected, the detection of small targets such as buoys and small boats become difficult. In general,
“Low” level should be selected.
