Joint angle and frequency estimation for linear array: an extended DOA-matrix method

An approach for joint direction of arrival (DOA) angle and frequency estimation a linear array is investigated in this paper. Specifically, we make the utmost autocorrelation cross-correlation information to propose an extended DOA-matrix (EDOAM) method. Subsequently, obtain auto-paired estimates by eigenvalues corresponding eigenvectors novel DOA matrix. Furthermore, proposed method surpasses which partly ignores information. Finally, works well both uniform non-uniform arrays. The simulation consequences indicate superiority our approach.
