Effects of Terrain on the Propagation of Microseismic Waves and Implantation Characteristics of Air-Delivered Sensors at Fort Huachuca, Arizona Wet- and Dry-Season Conditions
Abstract
To obtain a quantitative basis for experiment design decisions regarding evaluation of seismic intrusion detector (SID) systems, test areas were selected and special seismic and environmental field experiments were conducted. This report discusses the selection of the SID test areas, their wet- and dry-terrain characteristics, and the procedures for collecting environmental data and conducting seismic response tests (i.e. man-walking, drop-hammer, M151 wheeled and M577 tracked vehicles, ambient and induced noises). Also presented are experimental detection distance data on the hand-emplaced miniaturized SID (MINISID), and experimental data on the depth of penetration and angle of impact of the air-delivered seismic intrusion detector/short (ADSID/S). This report also presents a theoretical system for modeling the quantitative effects of the terrain on SID detection performance and methods by which SID test results can be extrapolated from one site condition to another. This system has been implemented on the AEWES computer and involves: (1) Acquisition of terrain and seismic data for input to the model; (2) Exercising the model for each set of terrain factor data; and (3) Portraying the performance predictions for each set of terrain and seismic factor data.
