Paper Abstract

Ground vehicle bearing determinations have been made using a single buried three-axis seismometer. The method is based on Rayleigh wave detection and exploits the phase difference between measured wave components. Maximum correlation values for the vertical component cross-correlated with horizontal beam components determine the propagation direction. Theoretical simulations demonstrate the technique. Two applications useful in monitoring vehicle traffic, vehicle velocity estimates and direction of travel (DOT), are also discussed. Comparisons of results obtained for several vehicles at different test sites are included.
