基于Kolmogorov等大气湍流模型，考虑到大气湍流引起的强度闪烁、光束漂移、扩展与抖动现象对激光通信系统性能的影响，利用数值模拟法中Zernike多项式法以及功率谱反演法模拟湍流随机相位屏。其中，Zernike多项式法模拟出的相位屏具有比较完备的低频成分，而功率谱反演法的相位屏功率谱中并不包含低频分量，会导致相位在大尺度起伏的情况下产生误差。所以还需要对相位屏进行低频补偿。结果对工程上研究大气湍流空间激光光通信的影响有一定的参考价值。

Based on Kolmogorov atmospheric turbulence ,taking into account the intensity of atmospheric turbulence caused by flickering beam drift and jitter affect the expansion of the laser communication system performance, using Zernike poly-nomials law and power spectral inversion method to simulate turbulent stochastic simulation method phase screen. Which, Zernike polynomial method to simulate the phase screen has a more complete low-frequency components, but the power spectral inversion method does not include the screen frequency power spectrum component will cause a phase error is gen-erated in the case of large scale fluctuations. So it is necessary to screen for low-frequency phase compensation. The results of atmospheric turbulence on space laser communication project on a certain reference value.
