Analysis of the architecture of the hardware and software complex for ground-based ionosphere radiosounding

“…The signal propagation occurs in the zone of the ionospheric radio line, after which it enters the receiver input. The technology of oblique sensing assumes that there is a distance of several thousand kilometres between the transmitter and re ceiver, which corresponds to changes in the transmission rate of a radio wave in the range of tens of milliseconds [12]. The received signal is processed in the frequency plane by compression, while it is multiplied by the signal of the receiving device.…”

“…The theoretical basis of this study is made up of available papers of Kazakh and a number of foreign researchers on problematic issues of constructing the architecture of a hardware and software complex for groundbased ionosphere radiosounding, to determine the optimal conditions of this complex when obtaining information about the processes occurring in the ionosphere, their influence on the nearby layers of the atmosphere, and the sequence of propagation of radio signals in the ionosphere [10][11][12]. To ensure the fullest possible perception of the information provided and to create an objective picture of research, all the developments of researchers taken in the order of citation and presented in this paper have been translated into English.…”
