Applications guide for propagation and interference analysis computer programs (0.1 to 20 GHz)

Ten computer programs useful in estimating the service coverage of radio systems operating in the frequency band from 0.1 to 20 GHz are reported. These programs were used to obtain a wide variety of computer-generated microfilm plots such as transmission loss versus path length and the desired-to-undesired signal ratio at a receiving location versus the distance separating the desired and undesired transmitting facilities. Emphasis was placed on the types of outputs available and the input parameter requirements. The propagation model used with these programs is applicable to air/ground, air/air, ground/satellite, and air/satellite paths. It can also be used for ground-to-ground paths that are line-of-sight or smooth earth.
