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.

中文摘要极化合成孔径雷达的回波信号可以提供不同收发极化状态组合下成像场景内目标散射波的幅度、绝对和相对相位、频率等信息，极化合成技术的出现使获取的信息量成倍增加，信息量增加的同时系统设计和信号处理的复杂度增加，因此极化合成孔径雷达相关技术的研究成为微波遥感领域的热点。
