| 英文摘要: |
| A novel modified MUSIC (MMUSIC) algorithm for high-resolution direction-of-arrival(DOA)estimation under amplitude and phase errors (array model errors) isstudied. The robust MMUSIC algorithm can improve the performance of DOA estima-tion compared with the original MUSIC. It is also easy to be implemented in practiceand is suitable for most cases of model errors. Computer simulations and experimentsare conducted to show the high performance in resolution and precision as well as thegood prospect in engineering applications of the MMUSIC algorithm. |
