INCOHERENT SCATTER FROM PLASMA OSCILLATIONS IN THE IONOSPHERE,
Abstract
In radar incoherent scatter investigations of the ionosphere, theory predicts that a small amount of power will be returned in a pair of sharp lines separated from the transmitted frequency by the electron plasma frequency. These 'plasma' lines are caused by scattering from longitudinal, electrostatic plasma oscillations. The observation of the plasma-line signal is reported and its large variation in intensity is discussed in terms of a nonequilibrium theory that allows for the presence of energetic photoelectrons.
