SELECTION OF OPERATIONAL MODES IN HF PROPAGATION PREDICTION.

Abstract

Criteria are given for selecting the operational sky -wave modes in hf propagation prediction for which the S/N 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)
