- W2364405802 abstract "Concerning the problem that the performance of direction-of-arrival(DOA) estimation using multiple signal classification(MUSIC) algorithm is decline seriously in the presence of array element position errors,this paper puts forward a scheme of DOA estimation in the presence of array element position errors,combining with particle swarm optimization(PSO) algorithm.In this scheme,firstly,the target functions are fitted in the principle of MUSIC algorithm,next,the functions are optimized using PSO algorithm and then the error matrix is corrected,and finally,the DOA estimation is performed using MUSIC algorithm.By comparing the simulation results with various parameters setting,a group that is of best estimation performance is selected as the key parameters setting for POS algorithm,and the DOA estimation performance of MUSIC algorithm before and after being standardized is contrasted in this paper.Simulation results show that the proposed scheme can improve the angular resolution of MUSIC algorithm greatly." @default.
