Abstract An upgrade of Wuhan Ionospheric Backscattering Sounding System (WIOBSS) was developed in 2015. Based on the Universal Serial Bus (USB), and a high performance FPGA, the newly designed WIOBSS has a completely digital structure, which makes it portable and flexible.

Ionospheric structure from oblique‐backscatter soundings
Radio Science, 1973Oblique ionograms are made monostatically by using an HF sounder to record the delay times of echoes from known ground targets as a function of operating frequency. Cooperative sources, such as repeaters, or distinctive terrain features, such as cities, serve effectively as known ground targets.
