Abstract

Abstract

This paper presents the speckle suppression technology which includes the soft threshold, the hard threshold and the Garrote function threshold method. It gives the contrast result of the three method. Analyzed the embedded zero-trees wavelet coding method, it presents a SAR(Synthetic Aperture Radar) image coding technology with the speckle suppression. Finally, it presents a compressed SAR image with the speckle suppression. The results show that the speckle of the SAR image is suppressed during coding the SAR image.
