Long duration finite-difference time domain (FDTD) simulations of seismic wave propagation from spatially and time varying sources are necessary to produce synthetic data of ground motion, data that is required for the development of unmanned ground sensor systems, which are the next wave in modern battlefield technology. We have generated data from moving synthetic sources that are typically found in a battlefield scenario, a generic representation of a moving tracked vehicle and a running human. The computational approach and requirements for the long-duration simulation including the geologic model, the moving vehicle force algorithm, the resulting particle velocity wave fields, and example applications of the data are discussed.
