摘要
卫星通信是现代通信的重要技术手段之一 ,其信号传输质量与大气层雨、雪致衰减密切相关。本文从理论和实际上介绍了雨、雪衰的成因及对卫星传输信号的衰落情况 ,并提出了有效降低雨、雪衰对卫星传输不利影响的措施。
As the satellite communication is an open communication system, the satellite link is subject to the impact of external conditions where the quality of signal transmission is closely related to atmospheric rain/snow attenuation. The author analyses both theoretically and practically the cause of the rain/snow attenuation and the fading of signal transmitted via satellite and detailedly introduces concrete measures to effectively reduce the adverse effects of rain/snow attenuation on the satellite transmission.
