| 摘 要： | 介绍了一种三通道权微扰谱估计测向方法。该方法首先利用权微扰方法来获得阵列的协方差矩阵,进而采用特征结构类算法估计波达方向,并采用空间平滑算法来处理相干信源。仿真结果表明,该方法的估计结果更加稳健、有效。且在接收机数目较少的情况下,该方法仍具有一定的实用性。

| Abstract: | A three-channel weight perturbation spectrum estimate direction finding（ DF） method is proposed in this paper. Firstly,the array covariance matrix is obtained by the weight perturbation algorithm. Then the eigenstructure based algorithm is employed to estimate the direction of arrivals. Coherent signals in correlated environment are coped with by spatial smoothing technique. The performance of the proposed method is evaluated by extensive simulations,and computer simulation results verify that the method provide more effective and robust estimation results. It offers a practical approach to direction finding in the case of fewer receivers being used. |
