He Weigang · Electronic Science and Technology · 2011
A new improved MUSIC algorithm for the estimation of the Direction-of Arrival of coherent signals sources is presented.After Eigen-value decomposing the receive data signal of coherence signals,the relationships between the signal subspace and the signal steering vector is used to achieve DOA effective estimation through searching the multidimensional wave peak.Compared with the traditional spatial smoothing algorithm,the IMUSIC has the following advantagesThe simulation results show the proposed IMUSIC algorithm is effective.
