极化滤波器

Test results using polarimetric SAR data of San Francisco show that images filtered by this method have mean values closer to the unfiltered images than with a subspace based filter. After the filtering process, targets with different scattering characteristics are more separable in the characteristic space; therefore, this filter improves terrain classification.

实验结果表明：利用旧金山地区的真实极化SAR数据，使用该方法滤波的图像结果与原有的子空间滤波器相比，更接近原始图像的均值，并且通过滤波提高了不同类别的目标在特征空间的区分度，从而有利于不同类型地物的分类。
