Ka 波段卫星通信雨衰问题的研究

介绍了影响雨衰的要素以及常用的雨衰预测模型---IT U-R模型，通过IT U-R雨衰预测模型，以扬州地区为例计算了雨衰大小，并通过M atlab进行仿真，分析了海拔高度、卫星纬度以及信号频率对卫星通信系统的降雨衰减特性的影响。

Research into The Rain Attenuation of Satellite Communication in Ka Band

T his paper introduces the factors influencing the rain attenuation and the common rain attenuation forecast model---IT U-R model ,calculates the rain attenuation magnitude taking Yan-gzhou area as an example through the IT U-R rain attenuation prediction model ,and performs the simulation by using Matlab ,analyzes the influence of height above sea level ,satellite latitude and signal frequency on the rain attenuation characteristic of satellite communication system .
