SAR图像相干斑空间域统计滤波算法的研究

Research on Speckle Statistical Filtering of SAR Image in Space Domain

合成孔径雷达 (SAR)图像相干斑噪声滤波技术分成三类 :多视处理、统计滤波和变换域滤波。本文总结了空间域统计滤波方法的数学基础和性能评价指标 ,并选择真实SAR图像作了对比试验 。

Synthetic Aperture Radar(SAR) speckle filtering techniques can be classified into three categories: multi-look processing, statistical filtering and filtering in transform domain. This paper deals with the statistical filtering category and the performance evaluation, makes a comparison study, and obtains some useful conclusions.
