Wavelet transform is a new applied signal processing technique in recent years, its time-frequency multi-resolution and signal processing performance are analyzed in the paper. A practical ground penetrating radar signal processing method based on wavelet transform is proposed; it contrast with continuous wavelet transform, the experiments indicate that it improves the processing performance of underground...
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...
