In this paper we introduced new wavelet based algorithm for speckle reduction of synthetic aperture radar images, which uses combination of undecimated wavelet transformation, savizat filter (which is an adaptive filter) and mean filter. Algorithm for speckle reduction of synthetic aperture radar images, which uses combination of undecimated wavelet transformation, wiener filter (which is an adaptive filter) and mean filter. The reduction of speckle is necessary for any further processing of SAR image. A new adaptive filtering algorithm is proposed to remove speckle in SAR images in this paper.
