Measurement setup:

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.

• Time domain filtering: Wiener SMI MRE 

  • Dimension: 128​

Reference signal reconstrution:

• None

Cross-Correlation detector:

• Method: Overlap and save

• Maximum range: 256bistatic range cell

• Maximum Doppler frequency: 559Hz

​​

Automatic detection:​

• Method: CA-CFAR

• Noise power estimation windows size: 6 x 6 cell

• Guard cells: 3x3 cell

• Threshold: 10 dB
