Frequency-dependent traveltime tomography for near-surface seismic refraction data
Geophysical Journal International(2016)
摘要
Traveltime tomography is the main method by which the Earth's seismic velocity is determined on all scales, from the near-surface (<100m) to the core. Usually traveltime tomography uses ray theory, an infinite-frequency approximation of wave propagation. A theory developed in global seismology to account for the finite-frequency nature of seismic data, known as finite-frequency traveltime tomogra...
