Abstract This paper employs quaternion theory to angle estimation of collocated bistatic MIMO radar. Quaternion model is constructed from the general data model, and the quaternion Root MUltiple SIgnal Classification (Root-MUSIC) algorithm is proposed for angle estimation in bistatic MIMO radar. This algorithm estimates Direction Of Departure (DOD) and Direction Of Arrival (DOA) via Singular Value Decomposition (SVD) and Root-MUSIC. The angle estimate performance of this algorithm is better than the existing algorithm, and the complexity of the proposed algorithm is reduced very much. The simulation results verify?the effectiveness?of the algorithm.
