Hardware Software System for Producing Coherent Bandwidth Maps of Transionospheric Wideband Radio Channel

Paper is addressed to the problem of taking into account the space-time variability of daily variations of coherent bandwidths for the transionospheric radio channel of satellite communications. We applied an analytical approach to the development of a mathematical model for computing coherent bandwidth in the transionospheric radio channel. An algorithm and a system that integrates hardware and relevant software for plotting regional digital maps of coherent bandwidths with the use of experimental data on the total electron content of the ionosphere were developed. There are presented experimental data on diurnal variations of coherent bandwidths over the Republic of Mari EI and Tatarstan.
