Abstract:

Criteria are given for selecting the operational sky -wave modes in hf propagation prediction for which the SN ratio is to be calculated. Only wave reflected from the F2 layer or the E layer are considered paths having reflections from both these layers are not considered. In the critical frequency calculations the number of control points varies with path length the maximum number is five. The program on which this study was based was written in NELIAC 5M for the CDC 1604 it is presented in AD-633 716. Author
