Abstract

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.
