In this paper, a new method named DSADE Despeckle with Anisotrpic Diffusion Equation which is based on anisotropic diffusion equation for SAR speckle reduction is proposed. With the local statistics values, DSADE provides anisotropic diffusion in the heterogenous area and isotropic diffusion in the homogeneous area. Thus, DSADE can not only preserve the edges and details, but also enhance them. In our experiment, DSADE is proved good performance in reducing speckle noise in SAR images and enhancing edges and details at the same time. Moreover, the filtered SAR images look good.
