Abstract

In this paper, the issue of two-dimensional (2D) direction of arrival (DOA) and two- dimensional (2D) direction of departure (DOD) estimation for bistatic multiple-input-multiple- output (MIMO) radar with cross array is investigated. A novel multidimensional angle estimation methods based on unitary transformation is proposed. Firstly, a new unitary matrix is designed using the central symmetry of cross array at transmit and receive site. Then both the rotational invariance relationships in transmit and receive array can be turned into the real-value field via the unitary transformation. And 2D-DOA and 2D-DOD joint estimations can be obtained. The proposed method, without costing the aperture of array and peak searching, can realize multi- dimensional angle estimation with automatic pairing and provides better estimation performance than ESPRIT. Compared with the traditional unitary transformation, the steering vectors of transmit and receive array can be turned into a real-value field via the unitary matrix and transformation in our scheme, respectively, Therefore, the proposed method can realize that the eigen-value decomposition and parameter estimation can be computed absolutely in a real-value field, with a result of a lower computation complexity. Simulation results verify the correctness of theoretical analysis and the effectiveness of proposed algorithm.
