A novel cohere, nt signal-subspace method for wideband signal location
A novel auto-focusing algorithm based on coherent signal-subspace method (CSM) is proposed. Subspace projection method is used to separate signals beforehand and auto-focusing process is done one by one. Data of different frequency bins are aligned in a fast way by develop the relationship between reference matrices and focusing matrices. While compared with the previous works,the proposed method avoids initial DOA estimation errors and needs no more SVD during updating. The experiment results show that it has better performance and modest computation.
