Paper Abstract

This effort is directed toward characterizing the response of a target-placed on or near the ground plane-to the radiation of a microwave source mounted on a moving vehicle. Because of the multipath problems inherent in measuring the electric field strength on or near the earth's surface, a theoretical model was constructed so that the effectiveness of the dynamic approach to actuating specific targets could be characterized. This process is repeated for a variety of microwave source speeds, vehicle-to-target-aspect ratios, and target positions on or above the ground plane. Given a horizontally polarized beam driven by a horn antenna, the electric field strengths were calculated at different vehicle-totarget- aspect ratios and at different heights on and above the ground plane for sand and clay soils. These values were then modeled in MATLAB to provide target stimulation for varied pulse chains. A model with independent pulse effects and a model based on the cumulative effect of pulses were evaluated.
