摘要
针对移动卫星系统的特点,分析了降雨引起的信号衰减的原因,给出了雨衰的计算方法。Ka波段一般用于移动通信业务,从分析结果上看该波段信号受降雨影响较大。提出几种补偿雨衰的方法,给出了上行功率控制法的系统原理图。
Aiming at the characteristic of MSS, the reason of signal attenuation by rain is analyzed and the calculation method of rainfall attenuation is given. Ka band is normally used for the business of mobile communications. Analysis result shows that the signal of this band gets rainfall influence greater. This paper puts forward several methods of rainfall attenuation compensation and gives the systematic principle figure of go up trip power control.
