TL;DR: In this paper, the authors extended the 2D wave-equation dispersion inversion (WD) methodology to the inversion of three-dimensional data for a 3D shear-wave velocity model, where the objective function is the sum of the squared wavenumber differences along each azimuth angle between the predicted and observed 3D dispersion curves.

TL;DR: In this article, Komatitsch and his loving family members have dedicated this paper to Dimitri and his family members, he is a light that has gone out much too early, and they also thank Ron Bruhn for his valuable advice about the geological explanation of their results.

TL;DR: This paper applies the UWB pulse radar to detect the periodic motion in through-wall detection, and presents methods based on the FFT and time-frequency analysis to detect periodic motions characters using the TWI data.

TL;DR: In this article, the interpreter can exploit some of the many opportunities available in surface waves recorded in land seismic data, such as the dispersion curves associated with surface waves, the common-offset gathers can reveal the presence of near-surface faults or velocity anomalies, and back-scattered surface waves can be migrated to detect the location of near surface faults.

TL;DR: In this article, the back-propagation algorithm is corrected with the analytical half-space far-field radiation pattern of an infinite line source to suppress undesired diffractive artifacts at the target edges.
