The MUSIC algorithm is researched in the planar antenna array. The conventional direction of arrival (DOA) estimation method in the planar array antennas uses the technology of beam scanning. It needs a lot of array element. To the finite conformal array DOA estimation, the resolution ratio will be affected by the Rayleigh limit. While, the MUSIC algorithm can fully utilize the orthogonality of noise subspace and signal subspace, it can achieve the DOA estimation through the spectrum peak search. Based on the planar array antenna, the Bartlett beam-forming method the capon minimum variance method and the MUSIC algorithm are analyzed and simulated. The simulation results show that the MUSIC algorithm has higher resolution relative to the two traditional algorithms.
