The problem of direction of departure and direction of arrival estimation for multiple-input multiple-output (MIMO) radar is discussed, and a reduced-dimension Capon algorithm is derived. The proposed algorithm which only requires one-dimension search, can avoid the high computational cost within the two-dimension Capon (2D-Capon) algorithm. It is illustrated that the algorithm has slightly better performance than the 2D-Capon algorithm. Simulation results verify the usefulness of the algorithm.
