| Abstract: | According to the ITU-R rain attenuation model,the rain attenuation model of geostationary satellite and the computation method for the long-turn statistical value of the rain attenuation model of non-geostationary satellite were given out.The simulation results using the rain data of the typical ground station in domestic showed that the model and computation method were correct.The study was valuable to the research and design of the satellite communication system in China. |
