中文摘要：

<正>This paper discusses the problem of direction of departure (DOD) and direction of arrival(DOA) estimation for a bistatic multiple input multiple output(MIMO) radar,and proposes an improved reduced-dimension Capon algorithm therein.Compared with the reduced-dimension Capon algorithm which requires pair matching between the two-dimensional angle estimation,the proposed algorithm can obtain automatically paired DOD and DOA estimation without debasing the performance of angle estimation in bistatic MIMO radar.Furthermore,the proposed algorithm has a lower complexity than the reduced-dimension Capon algorithm, and it is suitable for non-uniform linear arrays.The complexity of the proposed algorithm is analyzed and the Cramer-Rao bound (CRB) is also derived.Simulation results verify the usefulness of the proposed algorithm.

英文摘要：

This paper discusses the problem of direction of departure （DOD） and direction of arrival （DOA） estimation for a bistatic multiple input multiple output （MIMO） radar, and proposes an improved reduced-dimension Capon algorithm therein. Compared with the reduced-dimension Capon algorithm which requires pair matching between the two-dimensional angle estimation, the pro- posed algorithm can obtain automatically paired DOD and DOA estimation without debasing the performance of angle estimation in bistatic MIMO radar. Furthermore, the proposed algorithm has a lower complexity than the reduced-dimension Capon algorithm, and it is suitable for non-uniform linear arrays. The complexity of the proposed algorithm is analyzed and the Cramer-Rao bound （CRB） is also derived. Simulation results verify the usefulness of the proposed algorithm.
