Performance analysis of polarization space time cascade processing

Polarization-SpaceTime or SpaceTime-Polarization cascade processing can detect low velocity moving targets with polarized information on the received signal. To make a detailed analysis of the cascade processing, the adaptive weight is deduced. Then the detection performance against the cascade order, the space-time division and polarization division between the signal and clutter are qualitatively analysised, which would provide an instruction for choosing an appropriate cascade processing order. Simulation verifies the correctness of the analyzed conclusion.
