Multiresolution analysis for extended object speckle imaging

Along with specking imaging characteristic, by wavelet transform, multiresolution for extended object (satellite) speckle imaging is proposed in this paper. Form the simulation, the object feature at different scale is extracted. The satellite features on horizontal and vertical orientation become visible. Only the low-frequency sub-band images are used, the satellite outline is fairly good. Furthermore, for large size images, it may be a method to lessen the computational complexity and compress the images data under the tolerant conditions.
