Terrain Constraints on the Design, Testing, and Deployment of the GATOR Mine
Abstract
Tests of the GATOR mine in various terrains within the United States indicated that a non-uniform sensitivity existed in its AP seismic sensor. It was demonstrated that soil characteristics can affect sensor sensitivity, causing the mine to detonate when the target is beyond warhead lethal range, or causing it not to detonate at all. Using computer models that were validated through field studies, this report attempts to predict the expected sensitivity of the GATOR AP seismic sensor. A terrain matrix, made up of elements describing surface and subsurface terrain layers that affect target-induced seismic signal generation and propagation, was developed to define environmental parameter variation. Computer model signals were generated using the matrix results for input to the GATOR mine logic. The results were utilized to define mine- performance changes over the environmental parameter ranges. Terrain property combinations which have major effects on source-to-ground energy coupling and seismic signal propagation were evaluated using microseismic generation and propagation models. The models were validated to verify if they could realistically predict, with sufficient sensitivity and reliability, time domain signals versus terrain characteristics.
