High resolution exponential modeling of fully polarized radar returns

A method for modeling radar target scattering data for the purpose of automatic target recognition is considered. The approach is to estimate a time-domain feature vector which describes the target. The target is characterized by a set of scattering centers. Using the motion of a transient polarization response, scattering centers are estimated along with their polarization. An exponential model for the fully polarized radar return and estimation algorithm are presented
