To synthesize an oblique incidence ionogram, only those rays which reach the receiver were considered. With electron-density distributions, assumptions of the structure of the magnetic field, the off-great-circle profiles, and the choice of a magneto-ionic theory were made, and a program which takes into account the gross changes in the ionosphere along a path at sunrise and sunset, by the inclusion of the daytime E and Fl layers and specularly reflecting sporadic E layer, suffices. The Kift-Fooks method was used because the program could be run rapidly on a high-speed digital computer and the predictions could be made using the CRPL ionospheric propagation-predictions in their present card format on a highly automated basis. This program assumes a set of parabolic layers for the ionospheric profile and then calculates the ray path in or through a parabolic layer by the Appleton-Beynon equations.
