In this paper, a new direction of arrival (DOA) estimation method is proposed for uniform linear array when both uncorrelated and coherent sources are present. After the first eigen decomposition of the received data covariance matrix, the eigenvector corresponding to the maximum eigenvalue is used to construct a new matrix, by the second eigen decomposition of which, the DOAs of the uncorrelated...
A virtual multi-element uniform linear array is constructed through covariation matrix of the minimum redundant array in the presence of impulsive noise. Based on virtual multi-element uniform linear array and reconstructed covariation matrix, a novel orthogonal propagator method (OPM) is proposed. The proposed algorithm utilized few virtual elements and expanded the number of effective aperture array,...
