Radar target recognition using multiple bounce scattering terms

One of the most successful approaches to radar target recognition is based on the down-range radar cross section (RCS) profile of the target. A feature of the down-range profile is that some peaks relate to interactions between structures, as opposed to direct specular scattering. We propose a new method using interaction (multiple bounce) terms to compute a truly rotation invariant feature for radar targets to be used for recognition. We think that it presents a more reliable way of classifying radar targets which would trouble other recognition methods.
