一种解析的基于旋转矩阵估计的波达方向估计方法
An Analytical Direction-of-Arrival Algorithm Based on the Estimation of Rotation Matrix
摘要
Abstract
An analytical high-resolution direction-of-arrival (DOA) algorithm based on the estimation of rotation matrix(ERM) is proposed.In order to sufficiently utilize the concerning spatial temporal domain information to improve the performance of the algorithm,a set of correlation matrices of the received signals containing the rotation matrix and possessing diagonal structure is generated.These common complex-valued target matrices are transformed into real symmetrical ones through a series of matrix transformation operations to make use of ACDC to diagonalize the target matrices and to estimate the rotation matrix.The arrival angles could be further derived and the DOA goal could be finally reached.Simulation results illustrate that,compared with other existing state-of-the-art DOA algorithms,the proposed ERM possesses higher resolution and more accurate DOA estimation performance.关键词
