Real Time RF Propagation Simulation Support for AFSOR

Abstract

Recent research activities have been conducted to define the propagation and attenuation of communications signals through the atmosphere. These have, to a certain extent, allowed for the consideration of numerous factors, including multipath, ducting, diffraction, terrain, and weather phenomena. The Air Force Flight Test Center and the Navy Air Combat Environment, Test and Engineering Facility both require the capability to accurately represent the "real world" atmospheric propagation of communications signals for real-time Installed Systems Test Facility (ISFT) applications. This project developed methods for rapid efficient methods, algorithms and software to signal attenuation for the Joint Communications Simulator (JCS). The JCS is a real time simulator and thus the delivered software must provide propagation predictions for all relevant simulation players. Only those propagation predictions in which the loss displays a large change over a typical time step are evaluated. Thus, the terrain resolution and other first order environmental factors the determination of re-computation time for the simulation assets.
