摘　　要：根据地球站天线增益、天线效率、系统噪声温度以及降雨衰减对卫星链路性能影响的公式,开发了基于VB6.0的降雨衰减对卫星链路性能影响的仿真软件,基于此仿真软件,做了一系列Ka频段降雨衰减对卫星链路性能影响的模拟实验,通过对仿真结果的分析,探讨了雨衰对卫星链路的影响、功率控制策略等问题。According to the formula of satellite communication performance affected by antenna gain, antenna efficiency, system noise temperature of the earth station and rainfall attenuation, simulation software based on the effect of VB6.0 rain attenuation on the performance of satellite communication is designed. Based on the simulation software in this article, a series of simulation experiments to prove the effect of Ka band rainfall attenuation on the performance of satellite communication are conducted. Through the analysis of the simulation results, problems of the effect of rainfall attenuation on the performance of satellite communication and power control strategies are discussed here.
