摘要：

In this letter, the issue of direction of arrival (DOA) estimation for narrowband signals with two parallel linear arrays is discussed, and an extended DOA-Matrix method is derived. Specifically, the proposed method makes full use of the auto-correlation and cross-correlation information by constructing an extended DOA matrix. Subsequently, the auto-paired DOA estimates can be calculated by the eigenvalues and eigenvectors of the extended DOA matrix. Moreover, the proposed method outperforms the traditional DOA-Matrix method which partially neglects the auto-correlation and cross-correlation information. Simulation results are provided to validate the superiority of the proposed method.
