摘要：
A new technique using adaptive window for filtering of SAR images is proposed in this paper. It is based on developing mechanism of speckle whose lever varies with the reflectivity of scene property, Taking account of such scene heterogeneity, the proposed scheme to search homogeneous areas with increasing window and different thresholds works as perfectly as expected in, edge preservation and texture restoration of SAR images. The comparison between this new method and some well-known filters is also shown in this paper.
