Which preset is the right one?
Harbour
Should be selected when navigating in short range inside a harbour, sea clutter is usually
asymmetric and so it is processed with auto anti-sea clutter.
Near range
Should be selected when navigating with range scales < 3 NM. The system is always working
on short pulse. Echoes are enhanced to increase visibility. Sea clutter residuals are filtered by
scan to scan correlation.
Medium range
Should be selected when navigating with range scales from 3 NM to 12 NM, a standard anti-
sea clutter level is provided.
Long range
Should be selected when navigating with range scales > 12 NM, an increased anti-sea clutter
level is provided due to the long pulse use. Echoes are enhanced to increase visibility.
Rough sea
Should be selected in bad weather conditions with high rain downfall rates. The system is
always working on short pulse. Clutter residuals are filtered by scan to scan correlation with
the most effective setting. CFAR processing is applied over the radar video.
Ice
A special setting intended to increase the visualization of iced sea. Almost no video process-
ing is applied. The anti-sea control is disabled, but when enabled operates with a special
clutter attenuation curve.
