Gyroharmonic features of the hf-induced ionospheric irregularities

Abstract

Gyroharmonic features of the different-scale artificial plasma-density irregularities excited by HF modification of the ionospheric F2 region under conditions where the frequency of the O-mode pump wave is close to the fourth gyroharmonic frequency of electrons in the pump wave - plasma interaction region are considered. © 2012 Springer Science+Business Media New York
