Xuemin Yang, Guangjun Li, Zhi Zheng, Lang Zhong · Electronics Letters · 2014
A low‐complexity estimator for two‐dimensional (2D) central direction‐of‐arrival (DOA) estimation of multiple coherently distributed sources is proposed, which is based on applying the singular value decomposition method to the cross‐correlation matrix of the received signals at double parallel uniform linear arrays. The proposed estimator is performed with automatic parameter pairing. Simulation results confirm the efficacy of the proposed estimator.
