Summary

Acoustic-gravity waves in the ionosphere create moving, undulating, reflecting surfaces. Overhead passage of such surfaces causes variations of amplitude, phase, and frequency of reflected radio waves. The patterns of these variations change with the characteristics of the reflecting surface. For the study and prediction of these patterns, computer experiments were carried out to simulate the effects of sinusoidal reflecting surfaces on propagating radio waves. The simulated parameters included field strength and path length and its derivative. The results are compared with high-frequency measurements made over an oblique, ionospheric transmission between Ottawa, Canada, and Bedford Mass. (Author).
