This document describes a theoretical and experimental study of the interaction of high power, high frequency radio waves with the lower ionosphere. The theoretical calculations presented here show that the electron temperature of the ionospheric plasma can be greatly enhanced when the plasma is irradiated by a powerful groundbased HF transmitter with an effective radiated power of the order of 100 MW. If this plasma heating is maintained for times exceeding a few seconds, the composition of the plasma can also be altered. These temperature and composition modifications cause significant changes in the plasma conductivity and wave absorption in the medium. Two experiments were conducted in order to test for the predicted absorption and conductivity modifications: a vertical incidence plus absorption experiment and a nonlinear demodulation experiment. Data from the absorption experiment clearly show a large (9 dB) increase in wave absorption at 2.4 MHz due to a high power (60 MW ERP) HF heating of the ionosphere. The nonlinear demodulation experiment generated strong VLF radiation when the ionosphere was irradiated by a powerful modulated HF wave. These VLF signals are believed to be due to HF heating induced conductivity modulation of the dynamo current system. (Author).

This report describes the outcome of a preliminary study of non-linearities in the D-region ionosphere by heating the region with high power HF radio waves. Ultimate objective of the study was in determining the impact of the non-linear effects on radio communications, especially under highly disturbed ionosphereic conditions. Experimental work of 'Initial Phase' investigation dealt with the measurement of combination frequencies generated by the high power heating wave and a low power probing wave. Preliminary results of the measurement are presented. In addition to the experimental work, a theoretical feasibility study of the so-called wireless radiation system was made to determine its applicabilitiy to ELF and ULF radio communications. This radiation system is brought about by modulating the ionospheric current system using high-power HF heater. Numerical results of predicted radiated powers are also presented in this report.
