The reciprocity of Wuhan-Wanning and Wanning-Wuhan ionospheric HF channel is firstly analyzed by using Wuhan Ionospheric Oblique Incidence Sounding System (WIOISS). The WIOISS is a new type ionospheric oblique sounding radar based on the GPS time and frequency synchronization. The group delay and HF channel scattering function between the two ways is compared through the swept-frequency mode and fixed-frequency mode. Accordingly, based on the experiment results the Wuhan-Wanning link and Wanning-Wuhan link have a good reciprocity.%该文首次利用武汉电离层斜向探测系统(WIOISS)对武汉-万宁和万宁-武汉两条电离层高频信道的互易性进行了分析.WIOISS是基于GPS时间频率同步手段开发的新型电离层斜向探测系统,通过比较由系统扫频工作模式和定频工作模式得到的两条路径下的斜向传播群时延和电离层高频信道散射函数,可以得出武汉-万宁和万宁-武汉的电离层高频链路有较好的互易性.
