对均匀线阵接收一定距离的机器多噪声源得到的空间协方差矩阵提出一种修正算法，以重构在相同方位上的运场近似空间协方差矩阵。利用这种方法，通过改变陈列中心位置可确定机器多噪声源位置。计算机模拟实验证实方法的可行性。 A modified algorithm is proposed for the spatial covariance matrix obtained by a machine-borne noise source that receives a uniform distance from a uniform linear array to reconstruct the approximate space covariance matrix for the transport in the same orientation. With this method, the position of the machine’s multiple noise sources can be determined by changing the center of the display center. Computer simulation experiments confirm the feasibility of the method.
