A new Direction of arrival (DOA) estimation method for wideband coherent sources is presented in this paper. This method does not require any prior knowledge of the source number and initial estimation of source angles. In the proposed method, at first, upon calculating the focusing matrix, the covariance matrix of all frequency bins are transformed to the reference frequency. Then by forming a Hankel matrix for each signal subspace eigenvector (SSE), the de-correlation process is formed and the linear independent vectors are extracted from the Singular Value Decomposition (SVD) approach. The simulation results in different conditions shows that the proposed algorithm has better performance compare to other algorithms.

提出了一种新的宽带相干源到达方向估计方法。此方法不需要任何有关源编号和源角度的初始估计的先验知识。在提出的方法中，首先，在计算聚焦矩阵时，将所有频率仓的协方差矩阵转换为参考频率。然后，通过为每个信号子空间特征向量（SSE）形成Hankel矩阵，形成去相关过程，并从奇异值分解（SVD）方法中提取线性独立向量。在不同条件下的仿真结果表明，与其他算法相比，该算法具有更好的性能。
