Abstract 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.
