In the processing of Synthetic Aperture Radar （SAR） Images

a large window size

which is often used in estimating the local statistics of the image and filtering the speclke is needed. On the other hand

contrary

detection of edges and textural features often need small sized windows. Normal filters

which are intermediary ofthe two above

don’t give better results. This paper presents a new effective algorithm to solve the problem. In this method

the edges and the textural features of the SAR images are presented so the the problem of edge smearing in the normal filtering algorithm is avoid and the speckles are filtered effectively.
