SCATTER PROPAGATION OF RADIO WAVES PART 2
Abstract
The evidence regarding the nature of radio aurora, particularly that relating to the scattering mechanism is reviewed. Much evidence is found which supports the hypothesis that the ratio waves are scattered from electron density gradients produced by propagating ion-acoustic waves in the auroral ionization. Such waves could be generated by the auroral electrojet. Nevertheless there is another large body of evidence which cannot be explained by the existence of ion-acoustic waves. It is concluded that this evidence relates to occasions on which the radio waves are weakly scattered from electron density gradients randomly distributed throughout the auroral ionization. It is possible also that strong scattering sometimes occurs for radio frequencies near the bottom of the VHF band.
