Identification of a target in presence of ground clutter using polarization

Abstract

This article examines the polarimetric method of identification of a target in the presence of ground clutter. The clutter is modeled as a two-layer random medium. The complex scattering matrix for the clutter is obtained by using Born approximations carried to the second order to extract the crosspolarized scattered fields. The test target used is a loop of conducting wire oriented arbitrarily. It is found that the choice of polarization is one of the key factors if one has to identify targets in presence of clutter. This work does not take into account the mutual coupling between the target and the clutter sources. The important results are analyzed and discussed.
