In this paper, a new method which is based on anisotropic diffusion equation for INSAR phase noise reduction is proposed. With the local statistics values, the new method provides anisotropic diffusion in the heterogenous area and isotropic diffusion in the homogeneous area. In the experiment, the new method is proved good performance in reducing INSAR phase noise and preserves edges and details at the same time. Furthermore, the filtered INSAR phase can be unwrapped successfully.
