摘要
利用ITU-R给出的降雨衰减预测模型,根据我国主要城市的分钟降雨率数据,计算出我国Ka波段(30/20GHz),轨道位置为92°E的卫星通信系统在线极化波情况下的降雨衰减等值线分布,此结果可作为Ka波段卫星通信系统设计的理论依据。
Using the ITU-R rain attenuation forecasting model, and based on the rainfall data and the geographic location parameters of main cities in our country, the isograms of rain attenuation distribution for the communication satellite with the orbital location 92~ E in Ka band （30/20GHz） was presentd. A further analysis was made on the rain attenuation characteristic of the Ka band satellite communication system by integrating with the landform and the climate distribution pattern in our country. The results could be used as the theoretical basis when designing the Ka band satellite communication system.
