DOA Estimation Based on Weighted l<sub>1</sub>-norm Sparse Representation for Low SNR Scenarios

In this paper, a weighted l<sub>1</sub>-norm is proposed in a l<sub>1</sub>-norm-based singular value decomposition (L1-SVD) algorithm, which can suppress spurious peaks and improve accuracy of direction of arrival (DOA) estimation for the low signal-to-noise (SNR) scenarios....
