AD-ESPRIT for multi-target localization in bistatic MIMO radar system

In this paper, an ESPRIT-based approach named as AD-ESPRIT is presented to jointly estimate the directions of arrival (DOAs) and directions of departure (DODs) estimation of interesting multi-targets for bistatic MIMO radar system. The proposed method does not need two-dimensional (2-D) or multiple 1-D spectrum peak searching. Thus, the computational complexity of the proposed algorithm is reduced for the direction finding cross localization in bistatic MIMO radar system. Furthermore, the estimated DODs and DOAs is automatically determined. Simulation results are presented to verify the effectiveness of the proposed method.
