The term seismic interferometry refers to the principle of generating new seismic responses
by crosscorrelating seismic observations at different receiver locations. The first version of …

Classical seismological receiver functions are correlational or deconvolutional combinations
of vertical and horizontal component seismometer recordings of earthquake waves that …

In the 1990s, the method of time-reversed acoustics was developed. This method exploits
the fact that the acoustic wave equation for a lossless medium is invariant for time reversal …

Wavefield‐based migration velocity analysis using the semblance principle requires
computation of images in an extended space in which we can evaluate the imaging …

ABSTRACT A focusing acoustic wave field, emitted into a medium from its boundary,
converges to a focal spot around the designated focal point. Subsequently, the focused field …

The Marchenko integral, key to inverse scattering problems across many disciplines, is a
long-standing equation that relates single-sided reflection data and Green's functions for …

Correlation or convolution of recordings of diffuse fields at a pair of locations have been
shown to result in estimates of the Green's function between the two locations. Variously …

Various researchers have shown that accurate redatuming of controlled seismic sources to
downhole receiver locations can be achieved without requiring a velocity model. By placing …

Land seismic data are contaminated by surface waves (or ground roll). These surface waves
are a form of source-generated noise and can be strongly scattered by near-surface …

In this study, a comprehensive description of the adjoint formulation based on a systematic
use of Lagrange's identity is proposed to compute acoustic propagation effects induced by …
