阵列信号处理是信号处理领域内的一个重要分支，在近些年来得到了迅速发展。波达方向（Direction of Arrival，DOA）估计是阵列信号处理的一个重要的研究领域，在雷达、通信、声纳、地震学等领域都有着广泛的应用前景。在DOA估计的发展过程中，人们对高分辨DOA估计算法一直有很大的研究兴趣，并在这一领域取得了很多重要的进展。本文主要研究经典的多重信号分类（Multiple signal Classification，MUSIC）算法。 本文首先回顾了空间谱估计技术的发展过程及现状，比较详细的介绍了空间谱估计基础和DOA估计模型，研究了DOA估计中的MUSIC算法，给出了MUSIC算法的原理和步骤，并通过一些计算机仿真实验，得出了MUSIC算法的性能分析。最后做了全文总结，归纳了本文所做的工作和结论。(Array signal processing is an important branch in the field of signal processing. It has been developing rapidly in recent years. Direction of Arrival (DOA) estimation is an important field of array signal processing. It has a wide range of applications in radar, communication, sonar, seismology and other fields. In the development of)

说明：  通过控制风机的偏航角来减少对其后风机的尾流效应，从而达到整场出力最大化。在小型风电场很适用。(By controlling the yaw angle of the fan, the wake effect of the fan is reduced and the whole field output is maximized. It's very suitable for small wind farms.)
