激光通信中大气闪烁引起探测噪声的计算机模拟

Computer Simulation of the Detectiong Noise Caused by Atmospheric Scintillation in Laser Communication

大气湍流效应是光通信系统中不可忽视的一个重要问题,主要表现为大气闪烁、光束抖动、光束漂移等,这些现象都给探测系统带来附加噪声,使系统的接收灵敏度下降。本文主要讨论激光大气传输中强度闪烁效应(大气闪烁效应)的理论基础,以及强度闪烁的计算机模拟。

Atmospheric turbulence effect behaving as atmospheric scintillation, beam spreading and phase fluctuation etc is an important problem for the laser communication system.The phenomena make much additional noise on detecting system and reduced the sensitivity of receiver. The theoretical basis of the atmospheric scintillation on the atmosphere translation of laser is briefly discussed, and the computer simulation of the amplitude scintillation is given.
