摘要
针对空间平滑MUSIC算法会损失阵列的有效孔径且需要信源先验数目的问题,提出了一种新算法。该算法从矢量重构的思路出发,通过对接收数据协方差矩阵的最大特征向量进行矢量重构,即可实现不损失阵列孔径的解相干处理,同时利用全空间加权MUSIC算法,实现了信源数目未知下的相干信号准确定位。仿真结果证实了该方法的有效性。
A novel decorrelation algorithm that has^t aperture loss is presented. Through vector reconstruction by eigenvector of maximum eigenvalue, the algorithm can deal with coherent signal sources. Furthermore, using modified MUSIC algorithm based on whole space, high estimation capability can be acquired without knowing the number of signals. Finally, the computer simulation confirms the validity of the proposed algorithm.
