摘要
针对现有的对流层散射损耗模型中的缺陷,研究了雨、雪、雾等恶劣气象环境下,对流层散射通信的电波能量衰减。分析了传统晴空大气下对流层散射损耗的计算方法和变化规律,在恶劣气象环境下,研究了雨、雪、雾等恶劣环境下电磁波的衰减率计算方法以及变化规律。同时为避免路径计算的不合理性,研究了恶劣气象环境对应不同的电磁波路径模型。为全天候、各种气象条件下更好地实现对流层散射通信,建立具有一定参考价值的衰减模型提供依据。
To solve the shortcomings of calculating attenuation of troposphere communication,we analyzed the attenuation model of hydro-meteors:rain,snow and fog.We discussed the characteristics of those meteors.Then,we analyzed the way to calculate specific attenuations.And we proposed the method to calculate the path of electromagnetic wave in harsh weather.The consequence can provide help for establishing attenuation model of tropospheric communication,and also can improve communication quality.
