Aerospace propagation prediction capabilities associated with the IF-77 model
Abstract
The propagation model was incorporated into ten computer programs. These programs may be used to obtain a wide variety of computer-generated microfilm plots such as transmission loss versus path length and desired-to-undesired signal ratio at a receiving location versus the distance separating the desired and undesired transmitting facilities. Such capabilities are useful in estimating the service coverage of aerospace radio systems, and are currently being used to establish station separation requirements for VHF/UHF/SHF air navigation aids. This paper provides: (1) a brief discussion of the IF-77 propagation model; (2) a summary of the prediction capabilities available; and (3) remarks concerning model validation work.
