面阵中基于传播算子的二维DOA估计算法
Two-dimensional DOA estimation for planar array based on PM
摘要
Abstract
The problem of two-dimensional(2-D)Direction Of Arrival(DOA)is discussed for the planar array, and an algo-rithm using Propagator Method(PM)is proposed. The method constructs a new data matrix with correlation matrices of four sub-arrays in the planar array. Eigen-decomposition of the new data matrix is replaced by a linear operator to get the rotational invariance matrix, and then the estimation of azimuth and elevation are calculated. DOA estimation perfor-mance of the new method is better than the ESPRIT algorithm. Computational complexity is reduced, the utilization of receiving data and anti-interference ability is higher. In addition, the proposed algorithm can obtain automatically-paired 2D DOA estimation. Simulation results verify the validity of the proposed method.关键词
