Target discrimination method with polarimetric radar

Polarization diverse design of the transmit waveforms based on the property of the target scattering matrix provides better performance than transmitting waveforms with fixed polarizations. In this work, we study the target discrimination method under the active-decoys scenario with the polarimetric radar. The polarization diversity is employed in transmit antennas. We transform the target discrimination problem into a binary hypothesis problem. In the meanwhile, we study the vector discrimination model and scalar discrimination model. Otherwise, the discrimination probabilities for the true target and the false target are derived. Using numerical simulations, we demonstrate that optimal design of the transmitter polarizations provides improved discrimination performance over the radar with only horizontally and vertically polarized transmit antennas.
