摘      要：In the paper,polarization-sensitive array is exploited at the receiver of multiple input multiple output （MIMO） radar system,a novel method is proposed for joint estimation of direction of departure （DOD）,direction of arrival （DOA） and polarization parameters for bistatic MIMO radars.A signal model of polarimetric MIMO radar is developed,and the multi-parameter estimation algorithm for target localization is described by exploiting polarization array processing and the invariance property in both transmitter array and receiver *** making use of polarization diversity techniques,the proposed method has advantages over traditional localization algorithms for bistatic MIMO *** show that the performance of DOD and DOA estimation is greatly enhanced when different states of polarization of echoes is fully ***,when two targets are closely spaced and cannot be well separated in spatial domain,the estimation resolution of traditional algorithms will be greatly *** the proposed algorithm can work well and achieve high-resolution identification and accurate localization of multiple targets.
