This report presents and demonstrates a methodology for analyzing the frequency diversity dependency of a transmitted signal as a function of evaporation duct heights. The integrated Advanced Propagation (APM) module is used to compute maritime signal propagation loss, and a Nakagami-m model is used to model the fading channel. Several approaches for evaluating intermittent communications in maritime environments were presented and demonstrated. The authors show how the Navy-validated APM in combination with an effective channel model can predict maritime communications. Using this approach, simulation results showing the impact of evaporation ducts' wideband frequency diversity, as well as communication links states are presented. These types of analyses have very important applications in mission planning, and are a promising solution that can provide enhanced communication autonomy in unmanned maritime vehicles.
