Frequency-dependent traveltime tomography using fat rays: application to near-surface seismic imaging
C Jordi, C Schmelzbach, S Greenhalgh - Journal of Applied Geophysics, 2016 - Elsevier
Frequency-dependent traveltime tomography does not rely on the high frequency
assumption made in classical ray-based tomography. By incorporating the effects of velocity …

A case history: Application of frequency-dependent traveltime tomography and full waveform inversion to a known near-surface target
Traditional ray-theory-based infinite frequency traveltime tomography is likely to be invalid
for near-surface studies due to relatively long seismic wavelengths compared with the scale …
