| 摘 要： | 空间谱估计是对空间信号的波到达方向进行超分辨估计。而多重信号分类(MUSIC)算法基于对阵列天线输出信号的自相关矩阵进行特征值分解,通过谱峰搜索获得信号的空间谱。本文基于九元均匀圆阵对MUSIC算法进行了仿真,证明算法对模拟信号以及实际信号都具有良好的测向能力,为工程实现提供具有重要参考价值的技术基础。

| Abstract: | The spatial spectrum estimation is the super-resolution estimation to the direction of arrival airspace signal.Multiple signal classification(MUSIC) algorithm is a typical method of it.The self-correlation matrix formed by signals output from array antennas is decomposed by eigenvalues in MUSIC algorithm.Simulations of MUSIC algorithm based on uniform circular array of nine unites are carried out to demonstrate that the algorithm possesses high direction-finding capability to both analog signal and real signal.The results of experiments could provide the important technology foundation for the further engineering of the MUSIC algorithm. |
