| 摘 要： | 由于雨衰是影响卫星通信的重要因素,根据武警部队卫星通信网建设的需要,基于ITU-R制定的雨衰计算模型,选取6个典型城市进行雨衰计算,得到雨衰对Ku波段卫星通信系统的影响,分析得出地星路径仰角越小,海拔越低,降雨率越大,降雨造成的信号衰减越大。

| Abstract: | The rain attenuation is the main reason affecting satellite communication.Based on the requirement of armed police force satellite communication,using the ITU-R rain attenuation forecasting model,the article calculates the rain attenuation of six representative cities.By the result,it analyzes the main factors which affect the rain attenuation.The conclusion is that the rain attenuation will be graver,with the smaller antenna elevation,the lower altitude and the bigger rainfall.The article could be used as the reference for EIRP of armed police force satellite communication. |
