RADIO PHYSICS AND RADIO ASTRONOMY

Numerical simulations of the self-action of high-power continuous radio waves in the ionosphere caused by disturbances in electron temperature and density havebeen made for various frequencies, powers, and polarizations. It has been demonstrated that a major contribution to the self-action is made by the ionospheric D region where huge disturbances in electron temperature occur. In the E and F regions, the nocturnal electron temperature is also significantly disturbed, butthe self-action is relatively weak. The contribution to the selfaction from the disturbance in electron density at all altitudes is significantly smaller than that from the disturbance in electron temperature.

Key words: ionosphere, high-power radio emission, numerical simulations, amplitude self-actio
