This letter discusses the problem of Direction of Arrival (DOA) estimation for two-dimension antenna array, and derives a reduced-dimension multiple signal classification (MUSIC) algorithm therein. The proposed algorithm, which only requires one dimension search, can avoid the high computational cost within two-dimension MUSIC (2D-MUSIC) algorithm. We illustrate that the algorithm has very close performance to 2D-MUSIC algorithm without an accurate number of signals. Simulation results verify the usefulness of our algorithm.
