Abstract:This paper investigates the weak signal direction of arrival (DOA) estimation for an antenna array under strong interference signals, and a novel DOA estimation method is proposed for strong interference source suppression and weighted l1-norm sparse representation. The parallel adaptive beamforming algorithm based on power inversion is used to suppress strong interference and form a new array data, and the weighted matrix is determined according to the optimized subspace algorithm of the subspace projection. … Show more
