A Novel Ionospheric Sounding Network Based on Complete Complementary Code and Its Application [PDF]
Sensors, 2019 In this paper, complete complementary code (CCC) sequences are applied to a High Frequency (HF) ionospheric sounding network. Ionosondes distributed at multiple locations use the mutually orthogonal CCC sequences to conduct vertical soundings ...

VLF/LF Radio Sounding of Ionospheric Perturbations Associated With Earthquakes
Sensors, 2007 It is recently recognized that the ionosphere is very sensitive to seismic effects,and the detection of ionospheric perturbations associated with earthquakes, seems to bevery promising for short-term earthquake prediction. We have proposed a possible use

The Potential for a Networked Ionospheric Sounding Constellation
Space Weather, 2022 A novel networked sounding constellation mission concept is proposed. Radio sounding is the original sensing method that proved the existence of the ionosphere. Satellite‐borne sounders provided the first global observations of the terrestrial ionosphere

A new inversion algorithm for backscatter ionogram and its experimental validation [PDF]
Annales Geophysicae, 2014 Oblique backscatter sounding is a powerful tool for detecting and monitoring the ionosphere continuously at a remote distance. High-frequency (HF) backscatter ionograms provide the amplitudes of backscatter signals with respect to group path or time ...
