D region absorption effects during high-power radio wave heating
Abstract
Simultaneous solutions of the differential equations governing electron energy and power flow are used to study D region absorption effects arising from high-power HF heating. It is shown that self-absorption of the heating wave can severely limit HF heating of the upper ionosphere and that the power density available for heating above the D region saturates as the heating power is increased. Models of the electron temperature distribution under heated conditions are used to compute the change in two-way integral absorption on a 2.4-MHz diagnostic wave due to HF heating as a function of heating frequency. The predicted theoretical absorption change is found to agree with experimental results.
