The Interpretation of the Effects Return Focus in the Ionosphere on the Line Moscow – Rostov

Abstract

The paper presents the results of observation of the effects of refocusing on the line Moscow – Rostov, demonstrates the implementation of refocusing of the regular type in the ionospheric propagation of radio waves, not associated with the influence of traveling disturbance in the ionosphere. The possibility of nontrivial interpretation of mechanisms of ionospheric propagation of HF radio waves at reception of signals of exact time is analyzed.
