作为一种经典的DOA估计方法,MUSIC算法在所估计的信号为互不相干的窄带远场信号的前提下,能以较高的计算效率实现对信号的DOA渐进无偏估计,讨论了MUSIC算法的原理,并对其性能进行了仿真研究,得到了影响其估计性能的几种因素。
As a classical DOA estimation method, the MUSIC algorithm can realize DOA asymptotic unbiased estimation of signals with high computational efficiency under the premise of the estimated signals being non-coherent narrow-band far-field signals. The MUSIC algorithm The principle of this method is also studied. The performance of the simulation is studied and several factors affecting its estimation performance are obtained.
