说明：  对极化SAR图像进行原始PWF（极化白化滤波）处理，最终可输出一幅图像。 当然，输入输出都是雷达接收到的电场强度信息，要转化为图像还需要将其值转换为255灰度范围内。
(Polarization SAR images of the original PWF [polarization whitening filter] treatment, the final output image. Of course, input and output are the radar received electric field strength information, it is necessary to transform the image also needs to be converted to 255 gray value range.)
