Parameter
Definition/Description
Indicates the polarization of the
forward RF carrier. The value is
one of the following:
– ‘LinearHorizontal’
– ‘LinearVertical’
– ‘RCP’—right handed
circular;
– ‘LCP’—left handed circular.
Specifies the duration at which
the initial radiated frequency is
to be held (beginning at the
carrier start time) before the
frequency sweep begins.
NOTE – The initial radiated
frequency is defined
as the carrier rest
frequency plus the
value of the
sweepInitial-
FreqOffset
parameter, and
possibly
compensated for
Doppler.
Specifies the offset to be
applied to the rest frequency in
order to define the non-
Doppler-compensated radiated
frequency at the beginning of
the frequency sweep.
Specifies whether or not the
frequency is Dopplercompensated
following the
frequency sweep. The value is
one of the following:
– ‘fixed’—uncompensated
for Doppler;
– ‘DopplerCompensated’
—Doppler compensation
applied.
