Comparison of Full Wavefield Synthetics with Frequency-Dependent Traveltimes Calculated Using Wavelength-Dependent Velocity Smoothing
Autor: Jianxiong Chen, Colin A. Zelt
Publikováno v: Journal of Environmental and Engineering Geophysics. 22:133-141
Ray theory-based traveltime calculation that assumes infinitely high frequency wave propagation is likely to be invalid in the near-surface (upper tens of meters) due to the relatively large seismic wavelength compared with the total travel path leng

Detecting a known near-surface target through application of frequency-dependent traveltime tomography and full-waveform inversion to P- and SH-wave seismic refraction data
Autor: Priyank Jaiswal, Colin A. Zelt, Jianxiong Chen
Publikováno v: GEOPHYSICS. 82:R1-R17
We have applied a combined workflow of frequency-dependent traveltime tomography (FDTT) and full-waveform inversion (FWI) to 2D near-surface P- and SH-wave seismic data to detect a known target consisting of a buried tunnel with concrete walls and a
