利用极化相关系数从极化合成孔径雷达（Polarimetric Synthetic Aperture Radar，POLSAR）数据中提取城市和自然分布区的极化特征。基于反射对称性，极化相关系数有可能揭示地形的各种散射机制。为了验证极化相关系数的性能，分别在线极化和圆极化下，研究了城市地区和自然分布地区极化相关系数在几种极化散射模型下的行为，并得出了这两个地区极化散射特性的差异。实验结果表明，极化相关系数可以有效地从实际的L波段和X波段POLSAR数据中提取极化特征。
This paper attempts to use the polarimetric correlation coefficient for extraction of the polarimetric features of the urban areas and the natural distributed areas from Polarimetric Synthetic Aperture Radar (POLSAR) data. There is a possibility that the polarimetric correlation coefficient can reveal various scattering mechanisms of terrains based on the reflection symmetry property. In order to verify the capability of polarimetric correlation coefficient, we examined the behavior of this coefficient of the urban areas and the natural distributed areas with respect to the several polarimetric scattering models in the linear and circular polarization bases, and the difference of the polarimetric scattering characteristics between these two areas was derived. It was confirmed that the polarimetric correlation coefficient is useful to extract the polarimetric features from the actual L-band and X-band POLSAR data.
