Rice, “Prediction of Tropospheric Radio Transmission Loss Over Irregular Terrain: A Computer Method - 1968,” Technical Report ERL 79-ITS 67, U.S. Department of Commerce, Environmental Science Services Administration, Institute for Telecommunication Sciences and Aeronomy, July 1968.
Abstract: This report describes a computer method for predicting long-term median transmission loss over irregular terrain. The method is applicable for radio frequencies above 20 MHz and may be used either with detailed terrain profiles for actual paths or with profiles that are representative of median terrain characteristics for a given area. Estimates of variability in time and with location, and a method for computing service probability, are included.
Keywords: irregular terrain; transmission loss; tropospheric propagation; service probability; time availability
