Abstract

A 3D finite-difference time-domain model for elastic waves in the ground has been developed and implemented on a massively parallel computer. The numerical model has been developed as part of a project in which elastic and electromagnetic waves are used synergistically to detect buried land mines. The numerical model is used to study the interaction of elastic waves with buried land mines. As a first approach, a simple model for a TS-50 antipersonnel mine has been developed, and the interaction of elastic waves with the buried mine has been investigated. In both experimental results and numerical simulations, resonant oscillation occur at the location of buried mine. To further explore the resonant behavior of a buried land mine, a refined mine model has been developed that includes more details of the actual mine. Using the refined mine model, the nature of the resonance is explained, and the parts of the mien that influence the resonant oscillations are identified. Results are presented which describe the resonance as a function of burial depth and soil parameters.
