摘要
基于ITU-R的视距链路雨衰减数据库中的数据,本文提出了一种新的视距链路雨衰减的预报模式,给出了一种新的路径调整因子与不同时间概率雨衰减转换公式。与其他几种预报模式的比较表明,新模式与实验结果有更好的一致性。
Based upon the experimental data in ITU-R database, a new prediction model of rain attenuation for the terrestrial line-of-sight systems is proposed in this paper, where the new path adjustment factor and the new conversion formula for estimating the exceeded attenuation of other percentages of an average year from the exceeded attenuation of 0. 01 of an average year have been developed. Compared with several other models, this model has got better agreement with the experimental data.
