Buried object detection using surface waves\c William F. Stewart.

Abstract

The goal of this thesis is to evaluate the use of surface waves to detect buried objects. The source used to generate the surface waves was a three element phased array controlled by LabVIEW visual instruments. This research included developing a source and receiver, evaluating attenuation and azimuthal dependence of the surface wave propagation, detection using scattering within a tank of sand, and using the three element array to beamform surface waves. It was successfully demonstrated that target localization using surface wave scattering and beamforming with a phased array is possible. (MM)
