music算法的实现　MU S IC 算法是一种子空间分解算法, 它的各种性能已被广泛研究. 在信号波达方向估计领

域, MU S IC 算法的应用, 形成了MU S IC 波达方向估计算法. 实际应用中,MU S IC 波达方向估计算法, 拥有超分辨能力的同时, 也存在原理性缺点——MU S IC 空间谱不能反映目标信号的相对强度. 文中在前人工作的基础上, 对MU S IC 波达方向估计算法进行理论分析, 提出了有效的改进方法, 并通过仿真试验证实了分析的正确性.

-music algorithm MU S IC algorithm is a sub-space decomposition method, its performance has been extensively studied. In the field of signal DOA estimation, MU S IC algorithm applications, MU S IC formed DOA estimation algorithm . practical application, MU S IC DOA estimation algorithm, with super-resolution capacity, but also the existence of the principle of sexual shortcomings- MU S IC space spectrum do not reflect the relative strength of the target signal. text in the work of our predecessors on the basis of MU S IC on DOA estimation algorithm theoretical analysis, an effective method to improve and, through simulation analysis confirmed the correctness.
