Under the background that the Earth’s aerosphere contains Kolmogorov and non-Kolmogorov turbulence, it is significant to research the combined influence of these two kinds of atmospherical turbulence on laser-satellite communication. In this paper, based on the power spectra of refractive-index fluctuations for non-Kolmogorov turbulence in the free troposphere and stratosphere, using the extended Rytov theory, the scintillation indices of the spherical wave in the free troposphere and the stratosphere are derived, respectively, which are valid in all regimes of turbulent fluctuations. On this basis, using a three-layer altitude-dependent turbulent spectrum model for vertical/slant path describing the variations of turbulent statistical characteristics with altitude in the aerosphere, which is more accurate than the two-layer model, we present the scintillation index of a spherical wave propagating through Kolmogorov and non-Kolmogorov turbulence along laser-satellite communication uplink at large zenith angles and estimate the combined influence of Kolmogorov and non-Kolmogorov turbulence on the scintillation index. It is noteworthy that this expression is also valid in all regimes of turbulent fluctuations.

在地球大气层包含柯尔莫哥洛夫和非柯尔莫哥洛夫湍流的背景下，研究这两种大气湍流对激光卫星通信的综合影响具有重要意义。本文基于自由对流层和平流层中非Kolmogorov湍流的折射率波动功率谱，利用扩展的Rytov理论，分别推导了自由对流层和平流层中球面波的闪烁指数。 ，在所有湍流波动情况下均有效。在此基础上，针对垂直/倾斜路径，使用三层基于海拔的湍流谱模型来描述湍流统计特性随大气层高度的变化，该模型比两层模型更准确，我们给出了在大天顶角沿激光卫星通信上行链路通过Kolmogorov和非Kolmogorov湍流传播的球面波的闪烁指数，并估计了Kolmogorov和非Kolmogorov湍流对闪烁指数的综合影响。值得注意的是，该表达在湍流波动的所有情况下也是有效的。
