“…Since the data points collected manually or automatically on the leading edge of BSI can be uncontinuous and nonuniform in the ground distance, the contours of electron density distribution can present a fluctuated and unsmoothed feature, which is not real. However, large‐scale structures can still be caught by BSI inversion [ Zhao et al , ; Zhu et al , ].…”

Global Positioning System (GPS) computerized ionosphere tomography (CIT) and ionospheric sky wave ground backscatter radar are both capable of measuring the large‐scale, two‐dimensional (2‐D) distributions of ionospheric electron density (IED). Here we report the spatial and temporal electron density results obtained by GPS CIT and backscatter ionogram (BSI) inversion for three individual experiments. Both the GPS CIT and BSI inversion techniques demonstrate the capability and the consistency of reconstructing large‐scale IED distributions. To validate the results, electron density profiles obtained from GPS CIT and BSI inversion are quantitatively compared to the vertical ionosonde data, which clearly manifests that both methods output accurate information of ionopsheric electron density and thereby provide reliable approaches to ionospheric soundings. Our study can improve current understanding of the capability and insufficiency of these two methods on the large‐scale IED reconstruction.

“…Through the use of minimum group path delay theory, an automatic scaling algorithm of the swept-frequency backscatter ionograms was proposed by Song et al [ 113 ]. Moreover, many algorithms have been proposed to invert the leading edge of the swept-frequency backscatter ionograms to achieve the electron density profile, such as the inversion algorithm using simulated annealing [ 114 ], the ionospheric F 2 region inversion approach utilizing a single quasi-parabolic ionospheric model [ 115 ], or the IRI model combined with ray-tracing techniques [ 116 ]. In order to validate these inversion algorithms, several experiments were conducted by Zhou et al to make comparisons between the ionospheric electron density distributions reconstructed by GPS computerized tomography, backscatter ionograms, and vertical ionograms [ 117 ].…”

For decades, high-frequency (HF) radar has played an important role in sensing the Earth’s environment. Advances in radar technology are providing opportunities to significantly improve the performance of HF radar, and to introduce more applications. This paper presents a low-power, small-size, and multifunctional HF radar developed by the Ionospheric Laboratory of Wuhan University, referred to as the Wuhan Ionospheric Oblique Backscattering Sounding System (WIOBSS). Progress in the development of this radar is described in detail, including the basic principles of operation, the system configuration, the sounding waveforms, and the signal and data processing methods. Furthermore, its various remote sensing applications are briefly reviewed to show the good performance of this radar. Finally, some suggested solutions are given for further improvement of its performance.
