In this paper, a novel class of focusing matrices for the coherent signal subspace method is proposed. These matrices are formed based on a BP neural network and the concept of uniform focusing transformation of the direction-of-arrival (DOA) of wideband sources. The proposed DOA estimating procedure is efficient without prior knowledge of the DOAs.
