Polarimetric MIMO radar target detection

Polarimetric Multiple-Input Multiple-Output (MIMO) radar has multiple antennas of different polarimetric directions to transmit and receive signals. For signals in four transmit/receive polarimetric channels, the detection performance is studied via three target detection algorithms, i.e., the Bayesian optimal detection, the coherent accumulation detector and the noncoherent accumulation detector, on conditions that radar targets are anisotropy and two cross polarimetric channels have target returns with different amplitudes. It is found that polarimetric MIMO radar is more stable in target detection performance.
