High Resolution Exponential Modeling of Fully Polarized Radar Returns

Abstract

This report considers a new method for modeling radar target scattering data for the purposes of automatic target recognition. The approach is to estimate a time (range) domain feature vector which describes the target. In particular, the target is characterized by a set of attributed scattering centers using the notion of a Transient Polarization Response; not only are scattering centers and their energies determined, but also their polarization effects on a circularly polarized incident wave, which are in general elliptical. An exponential model for the fully polarized radar return and an algorithm to estimate those parameters are presented. This algorithm is then applied to compact range measurements of aircraft models, and the results are presented and discussed.
