摘要

闪烁指数(SI)是自由空间光通信(FSOC)的关键指标，用于测量大气湍流引起的归一化强度方差。它是折射率结构参数Cn2、范围和接收机孔径的函数。由于在环境中测试FSOC性能是困难且耗时的，因此需要一个大气模拟模型来模拟闪烁的影响。在本文中，我们将实验结果与使用相位屏的数值模拟结果进行了比较。实验结果与模型吻合较好。

Scintillation index of the free space optical channel: Phase screen modelling and experimental results

Scintillation index (SI) is a key metric for free space optical communications (FSOC), and measures the normalised intensity variance caused by atmospheric turbulence. It is a function of the refractive index structure parameter Cn2, range, and receiver aperture. There is a need for an atmospheric simulation model of the effects of scintillation because testing of FSOC performance in the environment is difficult and time consuming. In this paper we compare experimental results with numerical simulations using phase screens for channels involving three receivers of different size apertures. There is good agreement in the results of experiment and model.
