On the MATLAB platform, the multiscale curvelet transform is used to suppress the speckle noise of the SAR image. First, transform the image to logarithmic transformation and transform the speckle multiplicative noise into additive noise. Then an effective threshold denoising method is adopted to suppress the speckle noise very well, and the result is good.
