Time-varying inverse filtering of range-compressed radar signals

This document presents a novel deconvolution approach that is applied to range-compressed radar signals to enhance the range resolution of the backprojection images beyond the resolution limit given by the point-spread-function. Hence, this signal processing technique has certain super-resolution capabilities. The time-varying deconvolution scheme is based on a combination of the matching pursuit decomposition (MP-) algorithm and the inverse filter. In each iteration of the MP-algorithm the signal portion with the highest local signal energy is firstly reconstructed and then deconvolved by the inverse filter.
