Polarimetric Synthetic Aperture Radar measures the frequency, magnitude, absolute and relative phase of targets' backscattering signals in imaging scene for any possible combination of transmit and receive antennas. The polarization synthesis technique on one hand has greatly increased the acquired polarization information, on the other hand increased the difficulty of system design and signal processing.
