| 摘 要： | 为了使基于圆阵的MUSIC测向方法能够分辨相干信号,首先利用阵列变换的方法,将圆阵的阵列流形变成虚拟线阵的阵列流形,再利用处理线阵的空间平滑法对相干信号进行去相关的预处理,进而利用MUSIC算法就可以实现对相干信号的分辨.计算机仿真结果证明基于圆阵的MUSIC测向方法可以对相干信号进行分辨,这为基于圆阵的MUSIC算法的工程实现提供了具有重要参考价值的技术基础和数值结论.

| Abstract: | In this paper ,in order to resolve the coherent signals , the circular array was transformed into dummy form which was as alike as line array's firstly. And then, the coherent signals were wiped off cohering. Finally, the coherent signals would be resolved by MUSIC algorithm. The computer simulations showed that the coherent signals could be resolved by MUSIC algorithm used in circular antenna array. The results of experiments could provide the most important technology foundation and data verdict for the f... |
