Simulation and Comparison of Weak-Signal VHF Propagation

Space weather's intense variance has a seemingly random effect on radio wave propagation in the Very High Frequency (VHF) portion of the electromagnetic spectrum. In this paper, key models are developed to analyze and estimate performance of wireless systems in weak-signal propagation mediums. Chiefly, meteor burst communication, auroral propagation, and earth-moon-earth communication models are constructed and simulated with MATLAB. The experimental results are confirmed through experimental testing and data comparison. Overall, modeling of these space weather events is used in predicting the effectiveness of radio equipment through these weak-signal modes.
