An efficient ESPRIT-based method for two-dimensional direction-of-arrival estimation
Xiaodong Ye, Jintao Sun, Qiang Wang · 2002
In order to estimate two-dimensional (2D) directions-of-arrival (DOAs), a special 2D array has been designed whose elements can be extended by the second-order statistics of its received signals. The ESPRIT algorithm is effectively applied to the extended array for 2D direction-of-arrival (DOA) estimation. Simulation results confirm the proposed method.
