The maximum estimable number of sources of the traditional algorithms of Two Dimensional Direction-of-Arrival (2D-DOA) estimation have large amount of calculations, and the maximum estimable number of sources is strictly limited by the number of array elements. In this paper, with the co-prime L-shaped array, a sparse reconstruction method using the Khatri-Rao (KR) product is proposed. The 2D-DOA...
A new method is proposed for the source location with distributed sensor array. Firstly, the direction of arrival (DOA) of each subarray is estimated by the Multiple Signal Classification (MUSIC) group delay function. Secondly, the initial rectangular region is established from the DOA estimation. Finally, the regional contraction is performed based on the larger steered response power. The centroid...
