Abstract

Short-range RF propagation models with antenna elements placed at or near the earth's surface often fail to accurately predict path loss. Adequate mathematical models can be developed and validated to ensure deployed communication systems maintain link closure. Specifically, Unattended Ground Sensor (UGS) systems are deployed to be physically undetected, that is, the units are frequently buried with the antenna extended above earth's surface. This paper reviews the physical effects that determine propagation loss and synthesizes a mathematical model to predict this loss. These predictions are compared to real world propagation measurements in both open fields and in dense foliage for ranges up to 500m.
