Synthesis of a Layered Medium from its Acoustic Transmission Response
TLDR
In this paper, a direct method is presented to determine an acoustic layered medium from the seismogram due to a time-limited plane wave incident from the lower halfspace, which transforms the problem to the acoustic reflections problem as solved by Kunetz.Abstract:
A direct (noniterative) method is presented to determine an acoustic layered medium from the seismogram due to a time-limited plane wave incident from the lower halfspace. It is shown that one side of the autocorrelation of the seismogram due to an impulsive source at depth is the seismogram due to an impulsive source on the surface. This transforms the problem to the acoustic reflections problem as solved by Kunetz. Both the deep source time function and the layering can be determined from a surface seismogram.read more

Green's function representations for seismic interferometry
Kees Wapenaar,Jacob T. Fokkema +1 more
TL;DR: In this article, it was shown that the acoustic Green's function between any two points in the medium can be represented by an integral of crosscorrelations of wavefield observations at those two points.

Interferometric/daylight seismic imaging
TL;DR: In this paper, the authors generalized the daylight imaging concept to a theory of interferometric seismic imaging (II), which is defined to be any algorithm that inverts correlated seismic data for the reflectivity or source distribution.

Seismic interferometry-turning noise into signal
TL;DR: The field of seismic interferometry has at its foundation a shift in the way we think about the parts of the signal that are currently filtered out of most analyses as mentioned in this paper, the multiply scattered parts of seismic waveforms and background noise (whatever is recorded when no identifiable active source is emitting, and which is superimposed on all recorded data).

Tutorial on seismic interferometry: Part 1 — Basic principles and applications
TL;DR: In this article, it was shown that the autocorrelation of the transmission response at two receivers along the x-axis gives the Green's function of the direct wave between these receivers.

Spurious multiples in seismic interferometry of primaries
TL;DR: In this paper, the authors presented a derivation of the stationary phase principle of seismic interferometry for a homogeneous medium with one horizontal reflector and without a free surface, and showed that the correlation of the waves recorded at two receivers correctly gives both the direct wave and the singly reflected waves.
