Dynamic and Spectral Features of the Decameter Artificial Irregularities and the Stimulated Electromagnetic Emission over the ”Sura” Heating Facility near the Fourth Electron Gyroharmonic

摘要

The results of simultaneous studies of the dynamic and spectral characteristics of radio signals scattered off the decameter artificial striations with transverse scales l⊥ ~ 10–100 m to the geomagnetic field and the stimulated electromagnetic emission by a powerful action on the ionospheric plasma in the fourth harmonic region of the electron gyrofrequency on the Sura facility are presented.
