Abstract: This paper discusses the phenomena associated with signal attenuation through dust and foliage and quantifies the impact of these environments on signal propagation. Specifically, models used to characterize dust and foliage attenuation are developed and experimental data presented. Based on the model's results, conclusions are drawn concerning the relative impact of dust versus foliage on current satellite communications (SATCOM) links. Geopolitical events of recent years have given rise to an increased likelihood of operations requiring communications in these environments. Thus, the importance of these findings in today's world cannot be overstated. !31
