Abstract :
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.
