摘要

对卫星通信系统日益增长的需求导致较低频段变得更加拥挤。由于无线电通信系统的迅速发展,目前对10千兆赫以上频段的使用成为人们关注的焦点。而Rain是10ghz以上不同频率通信信号的主要衰减因子。降雨衰减对卫星通信系统网络的传播影响很大,需要慎重考虑。在规划微波卫星通信链路时,降雨衰减预测和降雨率是必不可少的。综述了微波和毫米波段卫星系统的雨率积分时间和雨衰减模型。关键词:频带,雨衰减,雨衰减模型,雨率,卫星系统

Rain Attenuation Prediction Models in Microwave and Millimeter Bands for Satellite Communication System: A Review
The progressively demand on satellite communication systems has consequently resulted in lower frequency bands getting more congested. The usage of frequency band beyond 10 GHz is in focus nowadays as a result of the rapid expansion of radio communication systems. However, Rain is the leading attenuation factor of different communication signal of frequencies beyond 10 GHz. Attenuation due to rain has a significant propagation effect that needs to be carefully considered in satellite communication system network. Rain attenuation predictions and rain rate are essential when planning microwave satellite communication links.  A review of the rain rate integration time and rain attenuation models for microwave and millimeter bands satellite system is presented. Keywords: Frequency Band, Rain Attenuation, Rain Attenuation Model, Rain Rate, Satellite System
