Ray-Tracing Analysis of a Line-of-Sight Communications Path.
Abstract
This report describes a ray tracing technique used to examine possible causes of a line-of-sight microwave link between Feldberg and Adenau, West Germany during the winters of 1975-76 and 1976-77. Use of the technique with various model atmospheres helped determine the significance of refractive bending and the location of radio holes. Estimates of the depth of the resulting fades showed that, on the average, fade was not significant. Results showed that fade can be expected whenever surface- based trapping layers extend to 1800 feet MSL. Antenna decoupling, another possible source, was not examined in this study.
