Abstract : In addition to the communication applications of FAS, ionospheric heating by powerful radio waves holds promise for establishing new techniques in the aeronomy of the D, E and F-regions. This report discusses the observed phenomena associated with the absorption of intense HF waves in the context of present theoretical understanding. The authors develop the fundamentals of ionospheric heating theory and apply it to the prediction of large scale electron temperature and density changes in both the D and F-layers. Generation of gravity waves by heating is also examined. (Modified author abstract)
