为解决散射通信在复杂环境中开通时间过长、链路估计和链路规划困难问题,结合对流层散射通信机理,分析了在复杂地形和气象环境下对流层散射通信链路损耗影响因素。根据ITU-R P.617最新成果,提出了一种适用于低散射角和高散射角的链路损耗计算方法,同时研究了雨、雾气象条件对链路损耗的影响及其计算方法。在华北地区搭建测试环境对分析方法进行了验证,结果表明该方法正确可行。
Abstract：In order to solve the problems of long time to preparing scatter communication in the complex environment,the factors influencing the link loss of tropospheric scatter communication in complex terrain and meteorological environment are analyzed based on the mechanism of tropospheric scatter communication.According to the latest version of ITU-R P.617,a method for calculating link loss is proposed,which is suitable for low scattering angle and high scattering angle.And the influence of weather conditions such as rain and fog on link loss is studied.The test environment is built in North China to verify the analysis method.The results show that the method is correct and feasible.
