Karazin Kharkiv National University popup.description2  The object of the research is atmospheric-gravity waves in geospace, the manifestation of which in its ionized component are moving ionospheric perturbations. The purpose of this report is to describe the breadboard model of the software-defined radio (SDR) system constructed for Doppler sounding the ionosphere remotely. The technique of simultaneous frequency-angle measurements has been implemented. The subject of research is experimental instrument for frequency-angular remote sensing of the ionosphere along oblique radio wave paths. Research methods: experimental and computer modeling. Research results: the block diagram of the 4-channel digital SDR receiver has been advanced, the breadboard model has been completed, the software environment has been chosen, and the needed software has been developed. The work was based on an existing prototype created by the team of authors in collaboration with experts from the Harbin University of Engineering (PRC). Due to the fact that SDR technology is characterized by exceptional flexibility and scalability, as well as by basic ability to integrate with information and computing tools, it is possible to significantly expand the diagnostic capabilities of the existing system by increasing the number of channels for simultaneous spaced radio wave reception along oblique radio wave paths (determining the angles of arrival of the radio waves). The development is expected to help create a relatively low-cost Ukrainian and global space weather-monitoring network in the future. The breadboard model of the system for sounding geospace along oblique radio wave paths significantly expands the research capabilities of the engineering base of the Department of Space Radiophysics to perform research, to improve training of highly qualified personnel, and to perform research projects and thesis research.
