METHOD OF CREATING RADIO CHANNEL THROUGH ARTIFICIAL IONOSPHERIC TRANSPONDER Russian patent published in 2014 - IPC H04B7/22 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio engineering. The method is based on that, along with probing the ionosphere with an inclined wideband linear frequency modulation probing signal, it includes irradiating the ionosphere with powerful radio radiation of a heating stand to generate scattering artificial small-scale magnetically oriented inhomogeneities in the ionosphere, which operate as an ionospheric transponder through which an additional radio channel is created. The pumping wave frequency of the heating stand is calculated based on conditions for aspect scattering of radio waves on the artificial small-scale magnetically oriented inhomogeneities taking into account coordinates of the location of a transmitter, a receiver of the wideband linear frequency modulation probing signal and the heating stand, using altitude-frequency characteristic data of the ionosphere, measured by a vertical probing station situated at the location of the heating stand.

EFFECT: wider operating frequency range and high reliability of short-wave radio communication.
