基于MUSIC算法的圆柱共形阵DOA估计
DOA Estimation for Cylindrical Conformal Array Antenna Based on MUSIC Algorithm
摘要
Abstract
Because of the influence of the curvature of cylindrical conformal array, the performance will be deteriorated and even become invalid when MUSIC algorithm is used to estimate signals DOA. The problem that the steering vector and the noise subspace are not orthogonal is efficiently solved by reconstructing the steering vector with directional of array element in consideration of the carrier's block. By contrasting with sub - array divided technique , Monte Carlo simulation and verification are done, and the estimation performance of MUSIC algorithm is analyzed. Finally, by taking the multi -layer column for example, the DOA estimation for four sources from different orientations are simulated and verified. The simulation results show that the method has the advantages of high differentiation and precision, also demonstrate that the proposed scheme is efficient and of high estimation performance.关键词
