A simple way for near-field source localization with MUSIC

In this paper, a method for neaivfield source localization based on MUSIC algorithm and high-order cumulant is proposed. Unlike other modified 2D MUSIC, the new method needs only one matrix to estimate the range and DOA, decreasing both the computational burden and complexity of the algorithm. Furtheremore, with high-order cumulant, it is also robust to coloured gaussian noise. The simulations show the effectiveness of the proposed method.
