Radar target characterization by the polarimetric high resolution method

摘要

We consider in this paper the characterization of a radar target by the high resolution method (MUSIC) with polarization diversity.udA stepped-frequency radar system is used and the target is modelled by the scattering centers . We propose a new high resolutionudmethod which exploits optimally the polarization of the received waves, the calculation time of this method is comparable to thatudof the scalar HR method . We show by simulation that the proposed method can not only give more informations about the targetud(polarization state), but also provide better performance than the classical scalar high resolution methods in terms of resolution ofudthe scattering centers .
