摘要：Direction-of-arrival (DOA) estimation of coherent sources is a significant problem in impulsive noise environments. In this paper, a robust estimation algorithm which combines the ideas of spatial smoothing (SS) and infinity-norm normalization (INF) is presented, referred to as INF-SSR. The proposed algorithm exploits the Root–MUSIC technique to computer the DOA estimates, thus avoiding the peak searching and can be applied to seriously impulsive noise environments compared with the fractional lower order moment spatial smoothing MUSIC algorithm (FLOM-SS). Simulation results demonstrate effectiveness of the proposed algorithm
