Abstract

The limitations of weak and distorted wave inverse scattering methods can be oversome using a signal processing based technique involving filtering of backpropagated field data in the differential cepstral domain. The purpose of this approach is to extract information about the scattering function from sets of products of this function with unknown field distributions. Being a nonlinear filtering method, there are difficulties in determining the optimal filter function for any given problem. This paper addresses this concern by presenting a systematic study of the information content of the differential cepstrum for a series of scatterers.
