Abstract : Computer Program Forest, is the computer adaption of a mathematical model to compute radio loss between two dipole antennas embedded in a forest environment for the 2 to 200 MHz frequency range. The model was reported in an article titled Radio Loss of Lateral Waves in Forest Environments by Dence and Tamir which appeared in the April 1969 issue of Radio Science. It assumes the transmission mode is a wave traveling laterally, at the forest-air interface, from the transmitting to the receiving site. The computer program is written in Fortran for use in the time-share mode on the Burroughs B5700 computer. A single frequency and single distance may be specified, or up to ten frequencies at from to ten distances may be called for. The program contains parameters to typify thin, average and dense forests, or the user can enter specific parameters when they are known. (Author)
