摘要：

Two-dimensional (2-D) direction-of-arrival (DOA) estimation method using three-parallel uniform linear arrays (ULAs) is proposed in this letter. The 2-D DOA estimation problem is addressed by making full use of elements of the three-parallel ULAs. Furthermore, the proposed algorithm has better angle estimation performance in practical mobile elevation angles between 70 and 90 and can automatically pair the estimated azimuth and elevation angles with lower complexity. Simulation results demonstrate the effectiveness of the proposed algorithm.
