基于均匀线阵,在不相关信号和相干信号共存的情况下提出了一种有效的测向方法.不相关信号的波达方向通过采用传统的多重信号分类方法(MUSIC)首先被估计.然后,利用空间差分矩阵构造了一个新的矩阵,通过对这个新构造的矩阵运用前向空间平滑技术进行处理就可以完成对相干信号的测向.提出的方法克服了空间差分方法内在的问题,其所处理的信号个数可以多于阵元的个数并具有良好的性能. Based on the uniform linear array, an effective direction finding method is proposed when the coherent signals and coherent signals coexist. The DOA direction of uncorrelated signals is first estimated by using the traditional multiple signal classification method (MUSIC) A new matrix is ​​constructed by using the spatial difference matrix, and the direction of the coherent signal can be obtained by processing the newly constructed matrix by using the forward spatial smoothing technique. The proposed method overcomes the inherent problems of the spatial difference method, The number of signals processed can be more than the number of elements and has good performance.
