Investigation of Low-Latitude Ionospheric Field-Aligned Irregularities by Oblique Backscatter Sounding

IEEE Geoscience and Remote Sensing Letters, 2010
The ionosphere is not homogeneous, hosting many irregularities with different scales from dozens of meters to dozens of kilometers. The observation and formation mechanism of the irregularities is among the most active domains for understanding the influence of irregularities on propagation of radio waves.

Design and implementation of hardware architecture in ionospheric oblique backscattering sounding system

Wuhan University Journal of Natural Sciences, 2009
The ionospheric oblique backscattering sounding system can not only be used to detect the state of ionosphere and the condition of high frequency channel in real time, but also be used for over-the-horizon sounding. So, it has a very high military and civil value.

Ionospheric structure from oblique‐backscatter soundings

Radio Science, 1973
Oblique 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.

Application of Wuhan Ionospheric Oblique Backscattering Sounding System (WIOBSS) for the investigation of midlatitude ionospheric irregularities

Advances in Space Research, 2018
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.
