AIRCRAFT-INDUCED IONOSPHERIC DISTURBANCES.
Abstract
Experiments were conducted to determine whether acoustic waves could propagate from the lower atmosphere into the ionosphere and be detected by hf radio waves. A supersonic aircraft was flown on a trajectory designed to focus the shock wave energy, generated over a long flight path, into a relatively small region of the daytime E-layer which was being probed by a phase path vertical sounder. Three series of tests, consisting of four flights each, were made. In each series, perturbations were found in the frequency spectrum of reflected radio waves that could be well correlated with the expected disturbance from aircraft-generated shock waves. (Author)
