Reference Processing:
Channel source:
-
Reference channel: From channel number 0
-
Surveillance channel: Beamforming from channel numbers: 1, 2, 3
Clutter cancelation:
-
Prefiltering: None
-
Beamforming: MVDR
-
The direction of the main beam is specified explicitly for all the CPIs according to
the real azimuth of the target, which has been obtained from FlightRadar 24 track data.
