Abstract :
A polarimetric method of identification of a target in the presence of ground clutter is examined. 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 cross-polarized scattered fields. The test target used is a loop of conducting wire oriented arbitrarily. It is found that choice of polarization is one of the key factors if one has to identify targets in the presence of clutter. The author does not take into account the mutual coupling between the target and the cluttering body. The results are analyzed and discussed.<>
