| 摘 要： | 研究了基于非均匀线阵的DOA估计问题。提出了利用修正MUSIC算法进行DOA估计,并设计了对称布阵方式。仿真结果表明在对称布阵非均匀线阵中使用修正MUSIC算法,空间谱分辨率高、栅瓣小,且分辨率要高于均匀线阵。本算法获得了较高的空间谱分辨率,提高了DOA估计性能。

| Abstract: | DOA estimation based on nonuniform linear array is researched.Modified MUSIC algorithm is applied to DOA estimation,arranging array symmetrically is designed.The simulation results indicate the space spectrum has low grating lobes,and the resolution is higher than uniform linear array.By the method proposed in this paper,high resolution of space spectrum is achieved,the performance of DOA estimation is enhanced. |
