摘　　要：本文提出了一种全极化散射中心提取与参数估计方法:P-MUSIC方法。该方法是一种极化和超分辨联合处理方法,不但能实现对各极化通道散射中心的数目、位置、强度以及归一化极化散射矩阵的同时估计,而且由于充分利用了目标全极化信息,还提高了散射中心提取和参数估计的精度。基于仿真和实测数据的实验结果证实了该方法的有效性。In this paper, a method which is called polarimetric-MUSIC （P-MUSIC） algorithm is presented for fully polarized scattering center extraction and parameter estimation. The P-MUSIC algorithm is a joint processing of polarization and super-resolution essentially. It is able to estimate the number, position, intensity and normalized scattering matrix of scattering centers instantaneously for each channel rather than the one which extracts parameters from every channel separately, and its performance is better than the latter because the fully polarized information is used. The validity is proved by the experimental results based on simulated and real data.
