Surface-Wave Group-Velocity Tomography for Shallow Structures
Journal of Environmental & Engineering Geophysics, 1999Because the Rayleigh waves generally have the largest amplitude of all waves generated by a vertical surface impact and because the near-surface shear-wave velocity primarily determines the Rayleigh wave velocity, the Rayleigh waves may be used to image shallow shear-wave structures.

Global surface wave tomography
71st EAGE Conference and Exhibition - Workshops and Fieldtrips, 2009I will present an overview of the state-of-art surface wave analysis which consists of three steps: (i) The measurement of the average dispersion between source and receiver (or between two receivers on the same great circle path) based on a non-linear waveform inversion.

IEE Proceedings - Radar, Sonar and Navigation, 1999
Techniques from two seemingly unrelated areas, X-ray transmission tomography and ground wave propagation attenuation (at much lower frequencies), are combined to produce a technique for imaging the dielectric properties of an inhomogeneous surface. A small-scale imaging experiment at microwave frequencies is described, demonstrating the potential for ...
