Tuning method Related options Description
– Antenna Boost:
scales the effective
antenna size. At
zero, the effective
antenna size
matches its actual
size. At 95%, the
effective antenna
size is doubled.
Increasing the
effective antenna
size separates
targets that appear
merged at lower
settings.
– Power Boost:
adjusts effective
transmit power.
At zero, the
radar operates
at its standard
power (4kW or
12kW). At 90, the
effective power
is increased by a
factor of at least
two. Increasing
the power makes
targets more
distinct from noise.
For maximum
benefit, reduce
power boost to
prevent saturation
of strong targets.
