摘要
根据ITU-R雨衰预测模型,给出了静止轨道卫星降雨衰减预测模型和非静止轨道卫星降雨衰减长期统计值计算方法。结合我国典型地面站的降雨率数据进行的仿真结果表明:所用模型和方法正确。研究对我国卫星通信系统的研究与设计有一定的参考价值。
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.
