We present a signal processing approach for generation of multilook SAR intensity images at dyadic scales of resolution. Orthogonal subband decomposition inherent in discrete wavelet packet transform is utilized in shift-invariant manner to produce multiresolution complex SAR images. The symmetry of detailed subband spectra is utilized in separating the disjoint spectra to produce multilook image. Analytical results and sample imagery of diffused reflection are presented.
