On the forward scattering of radio waves in the lower ionosphere

Abstract

A method is developed whereby it is, in principle, possible to separate the two main signal domponents in VHF ionospheric forward scatter propagation. The method is based on a study of the angular power distribution of the received signal. From exp eriments made over a circuit of 1,180 km the law of turbulent scattering is determined. The spectrum for the electronic irregularities is found to be given by k -?' with n~9 under the experimental conditions described .

“…Measurements on a north-south path by Hagfors [1962] show that at midday most of the meteor bursts are received from the eastern side of the path whereas around midnight the majority of the bursts are from the west side of the path. At both times a minimum in the number of bursts was seen along the great circle path.…”
