大气层传播因素对卫星通信的影响分析

随着时代的发展,卫星通信越来越深入到人们的生活、工作和学习中。文章基于电磁散射的理论,从降雨引起散射和吸收,降雨衰减的预测,雪、雹或雾的影响以及晴空效应和大气效应四个方面,探讨与阐述了大气层传播因素对卫星通信的影响。对宽带多媒体无线通信、宽带无线接入的个人通信、卫星系统的设计以及远程教育工程的维护有较好的参考价值。

Analysis of impact of atmosphere spread factors to satellite communications

With the development of the times,satellite communications have increasingly deepened into people's life,work and study,based on the theory of electromagnetic scattering the impact of atmosphere spread factors to satellite is probed into and expounded from four aspects: absorftion and scattering caused by rain,forecasting of rain attenuation,affect of snow,hail or fog,and clear-air effect and atmosphere effect.It has a good reference valuc for broadband multimedia wireless communication,broadband wireless access personal communications,satellite system design,and maintenance of remote education project.
