Formulation of the problem. Resonances in the Earth-ionosphere waveguide were experimentally confirmed by Schumann in 1960. To date, a significant number of oscillograms and spectrograms of Schumann resonances have been recorded, but the registration of Schumann resonances is associated with certain technical difficulties due to small amplitudes and the presence of additive noise.

Target. Find a solution for determining the coordinates between the source-receiver correspondents. Show that the amplitude of the first Schumann resonance does not depend on the distances between the correspondents.

Results. The paper solves the inverse problem of restoring excitation sources (electromagnetic radiation of lightning discharges).

Practical significance. The use of this method of analysis in systems for recording Schumann resonances makes it possible to identify single lightning discharges from other sources of oscillations and it is possible to determine the distance to the source without using a notch from spaced reception points using the radiation patterns of magnetic field recorders.
