摘要
研究了逆向调制光通信回波反射链路中的大气湍流效应及抑制方法。利用相位屏方法模拟大气湍流效应, 建立了弱湍流情况下高斯光束在传统无线光通信和逆向调制光通信中的传播模型, 对比分析了高斯光束在传统自由空间光通信单向链路和逆向调制光通信双向链路中大气湍流引起的闪烁指数。结果显示大气湍流对逆向调制光通信回波反射链路的影响远大于对传统自由空间光通信中单向链路的影响。还研究了孔径平均效应对逆向调制光通信中回波反射链路中闪烁指数的影响。结果表明, 对于逆向调制光通信, 大的接收孔径对于大气闪烁的抑制依然有效。
Abstract
The effect of atmospheric turbulence and its suppression methods in traditional free space optical communication link and modulating retro-reflector optical communication link were studied. The phase screen method was used to simulate the effect of atmospheric turbulence, and the propagation model of Gaussian beam in traditional free space optical communication link and modulating retro-reflector optical communication link was established. The scintillation index of Gaussian beam influenced by atmospheric turbulence in free space optical communication link and modulating retro-reflector optical communication link was compared and analyzed. The results show that the influence of atmospheric turbulence on echo reflection link in modulating retro-reflector optical communication is much greater than that of link in traditional free space optical communication. The scintillation index influenced by the average aperture in echo reflection link of the modulating retro-reflector optical communication was also studied. The results show that the large receiving aperture is still effective for the suppression of atmospheric scintillation in modulating retro-reflector optical communication.
