Abstract : This report summarizes research on the Effects of the Aurora on Radio Wave Propagation. The research included a detailed theoretical study of the generation of synchrotron noise by auroral electrons spiralling in the earth's magnetic field. Experiments were conducted to detect iongyro modulation on radar returns from field aligned irregularities such as those associated with the aurora. A model of auroral radar reflections is discussed which hypothesizes acoustic waves excited by current streams which flow in the ionization enhanced regions at the base of auroral forms. A study was made of the effects on radio wave propagation of high velocity streams of electrons such as those in the solar wind. (Author)
