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 prediction model of rain attenuation of ITU-R, the prediction model of rainfall attenuation in geostationary orbit and the method of long-term statistical calculation of rainfall attenuation in non-geostationary orbit are given. The simulation results based on the rainfall rate data of typical ground stations in China show that the models and methods used are correct. Research on China’s satellite communications system research and design have some reference value.
