IONOSPHERIC PROPAGATION STUDIES.

Abstract

A relation for the condition of minimum time delay focussing for the spherical earth geometry is obtained assuming on ionosphere with a parabolic distribution of electron density. Theoretical curves for the case of sweepfrequency backscatter are obtained that agree well with experimental values. A qualitative explanation of frequency independent echoes is given in terms of the flat earth and ionosphere approximation. Unusual cases of motions of this frequency independent echoes are discussed and explained. The diurnal and seasonal variations of backscatter echoes from the south for the years 1962 and 1963 is given and discussed. (Author)
