摘要：
In this paper, we enhanced the performance of the iterative minimum mean square error filter (IMMSE) in terms of speckle suppression and detail retaining by establishing another version of the minimum mean square error MMSE estimator and adapting the iterative procedure to the non -local structure similarity. The non-local principle is introduced in the calculation of the IMMSE filter parameters. Simulated and Spaceborne (Sentinell Amdoun region-Tunisia) high-resolution synthetic aperture radar SAR data were used for validation.
