Numerical Simulation of Ground-to-Satellite Laser Transmission based on Unequal Spacing Phase Screen

In this paper, the numerical simulation method of multilayer phase screen step-by-step transmission is used to study the influence of atmospheric turbulence on the upstream transmission of satellite-ground optical communication. The model of atmospheric turbulence laser transmission between satellite and ground is established to simulate the laser transmission between ground terminal and Low-Orbit satellite. Unequal spacing phase screen is used to simulate non-uniform turbulence. The simulation calculation of optical transmission under different turbulence conditions with different zenith angles can be realized. The simulation results of the satellite upstream optical communication verified the model.
