Measuring and Analyzer of Rain Attenuation for Satellite Communication in Ku band
Using a rain gauge, spectrum analyzer and other equipments, rain rate and rain attenuation for the satellite communication signals in Ku band(14/12GHz) in Wuhan city are measured and analyzed simultaneously according to simulations. The relation between rain attenuation and rain rate are analyzed, the result is compared with the estimated International Telecommunication Union Radio Communication Sector (ITU-R) and the difference between the prediction and the measuration is analyzed. To the inaccuracy of the forecasting model, a modified algorithm is presented and by using the data measured, the ITU-R forecasting model is corrected. The experiment results suggest it is necessary to measure for long time to get enough data of the relation between rain attenuation and rain rate at different stations.
