- Аннотация: The paper presents the results of numerical simulation of the propagation of HF radio waves in an artificially disturbed ionosphere during Cyclone-3 vehicle launch from the Plesetsk cosmodrome on December 18, 1991, powerful industrial explosion on the Kola Peninsula on April 8, 1990 and ionospheric modification experiment at the SURA heating facility on August 18, 2011. Radiotomographic crossections show that artificial ionospheric irregularities during the studied events are quasi-wave perturbations that have a significant effect on the ray paths of the HF radiowaves and ionograms of vertical and oblique sounding. This manifests itself in the form of characteristic features of HF ray paths including artificial waveguides to the outer ionosphere heights, multiple reflections from local maxima of the electron density and additional traces on ionograms caused by the passage of traveling ionospheric disturbances.
