| Abstract: | Aiming at the problems of the high resolution methods in practice,such as large computation,poor resolution in low snr and sensitivity in the case of modeling errors,the algorithm of combining normal beam-form and high resolution methods is researched.The beam-space MUSIC algorithm is introduced and the statistical analysis by computer simulations is given.The relation between beams and the threshold for estimating the direction are analysed and proved.The simulation results show that the beam-space algorithm has good performance,such as low computation and high resolution in low snr. |
| Keywords: | beam-space DOA high resolution estimation beam-forming |
