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)
