【摘要】 本文从空间光通信中大气信道对激光传输的影响出发,研究了大气消光造成的激光功率衰减问题,并对各种能见度下的大气信道衰减特性进行了计算和分析;分析了大气湍流对激光传输的影响,给出了影响通信系统性能的四种大气湍流效应及对应的理论计算模型,通过仿真分析了不同条件下的大气湍流影响结果,并通过野外实验计算了不同孔径、不同时间下的光强闪烁和折射率结构常数,仿真结果与外场实际实验具有一致性。更多还原

【Abstract】 Based on the Atmospheric effects on the space optical propagation communication in this paper,the problem of power attenuation caused by atmospheric extinction was researched,and the attenuation characteristics of the atmospheric channel with various visibility distances were calculated and analyzed.The turbulence-induced effects on the Laser propagation were systematically researched,and five kinds of turbulence effects and their mathematical models were discussed.Then,simulation results of turbulence effects under various conditions were analyzed.Then the Intensity scintillation and atmospheric structure constant was calculated by the different aperture and from different data through the wild experiment,The Simulation results show consistency with theory analysis.更多还原
