An adaptive spatial spectrum estimation based on spectral peak separation

A high-precision algorithm on the estimation of DOA is presented in this paper. According to the theory of adaptive filtering and beam forming and RLS fast iteration algorithm and the technology of spectral peak separation, we establish a suitable spatial spectral function and search the spectral peaks to distinguish the directions of signals in this paper. The computer results show that the new algorithm can be applied to uniform linear array and uniform circular array. The accuracy is higher than that of MUSIC.
