AD-MUSIC for jointly DOA and DOD estimation in bistatic MIMO radar system

In this paper, a MUSIC-based approach named as AD-MUSIC is presented to jointly estimate the directions of arrival (DOAs) and directions of departure (DODs) estimation for the direction finding cross localization of multi-targets in bistatic MIMO radar system. The MUSIC algorithm for the DOD estimation is referred to as the D-MUSIC algorithm. On the other hand, the A-MUSIC, which estimates the DOA, is introduced as well. The proposed AD-MUSIC combines two one dimensional (1-D) MUSICs along with the spatial beamforming technique to jointly estimate the DOAs and DODs. At the same time, the estimated DOAs and DODs is automatically determined. Simulation results are presented to verify the effectiveness of the proposed method.
