Abstract

Abstract: The scope of this work is to analyze methods for increasing radar-contrast between
different scattering object surfaces . Methods for radar contrast enhancement by polarization
analysis of the scattered signal, i. e, radar contrast control, orthogonalization and polarization
compensation methods are analyzed in this paper for deterministic and stochastic cases, and
compared with conventional RCS radar analysis. The results of the analysis show that radar
contrast obtained by using polarimetric methods is enhanced compared to conventional RCS
analysis, and indicate that to enhance contrast it is necessary to control the receive-transmit
antenna polarization according to changes in the polarization state of the transmitted and the
received waves.
