Direction Finding of Propagator Method Using Adaptive Cultural Algorithm in the Impulsive Noise
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, while significantly improving the performance of the original OPM algorithms. In order to fit the proposed direction finding algorithm based on the minimum redundant array and covariation matrix, an adaptive cultural algorithm is designed for objective function of direction finding. Monte-Carlo simulations have proved that the proposed method has some good performance such as high resolution in the presence of impulse noise and the capability of using a small number of elements to find more signal sources.
