 The purpose of this report is an approbation of the breadboard model of the system for the multi-channel passive Doppler sounding of the ionosphere along oblique radio wave paths on the principles of frequency and angular remote sensing in the study of ionospheric disturbances of various physical nature, as well as the formulation of recommendations for its inclusion in an extensive network of continuous monitoring and warning of travelling ionospheric disturbances passage over Ukraine. The subject of research is experimental hardware and software for frequency and 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. Performed experimental studies of travelling ionospheric disturbances, which arise under the action of powerful sources of various physical origins, have demonstrated the prospects of using the breadboard instrument for regular space weather investigations and the development of existing models of processes in geospace. It is expected that the breadboard instrument will help expand the capabilities of the existing global space weather monitoring network and build a relatively inexpensive Ukrainian 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.
