Result:
The relative exclusion zone is
predominantly used to avoid sea
clutter at close range (smaller 3
NM). However, not only sea clutter
but also small targets can be
suppressed. The Radar user must
be aware of this situation.
This example shows a ring centered at own ship, which is
useful when the sea conditions produce numerous false
alarm echoes from waves. The exclusion zone will inhibit
the auto acquisition function. This function can be used to
eliminate the acquisition of false echo effects.
The range area can be individually adjusted using the
editing marks or the text slider.
