A Novel Ionospheric Oblique-Incidence Sounding Network Consisting of the Ionospheric Oblique Backscatter Sounder and the Parasitic Oblique-Incidence Sounder

IEEE Geoscience and Remote Sensing Letters, 2015
In this letter, a novel ionospheric oblique-incidence sounding network consisting of the ionospheric oblique backscatter sounder and the parasitic oblique-incidence sounder is presented. With the new configuration, the oblique ionogram and the backscatter ionogram can be provided at the same time.

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.

Development of a Method for Determining the Position of Artificial Ionospheric Irreguliarities Responsible for the Radio-Wave Aspect-Angle Scattering on Short Paths by Oblique Backscatter Sounding Ionograms

Izvestiya vysshikh uchebnykh zavedenii. Radiofizika, 2021
The data of experiments on the oblique backscatter sounding of the heated ionospheric volume above the Sura facility on a short Kazan—Vasilsursk—Kazan path, when the Cyclone-GPS ionosonde was operated in the ionogram recording regime in the frequency range 1–7 MHz with a step of about 20 kHz are compared with the results of ray-tracing calculations for

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.
