Comparison of four techniques for estimating temporal change of seismic velocity with passive image interferometry [PDF]

open access: yesEarthquake Science, 2010
Passive image interferometry (PII) is becoming a powerful tool for detecting the temporal variations in the Earth’s structure, which applies coda wave interferometry to the waveforms from the cross-correlation of seismic ambient noise. There are four techniques for estimating temporal change of seismic velocity with PII: moving-window cross-correlation

Passive Seismic Interferometry as a Tool for Seismic Imaging from Mine Galleries

83rd EAGE Annual Conference & Exhibition, 2022
To test passive seismic interferometry (PSI) in underground mining environments, we carried out an active-source seismic and continuous noise measurement in a mine gallery of a former radioactive waste repository - the Asse II salt mine (Lower Saxony, Germany).

Comprehensive observation and modeling of earthquake and temperature‐related seismic velocity changes in northern Chile with passive image interferometry [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2014
AbstractWe report on earthquake and temperature‐related velocity changes in high‐frequency autocorrelations of ambient noise data from seismic stations of the Integrated Plate Boundary Observatory Chile project in northern Chile. Daily autocorrelation functions are analyzed over a period of 5 years with passive image interferometry.

Seismic interferometry, with applications in passive reflection imaging

The Journal of the Acoustical Society of America, 2005
Seismic interferometry is the process of generating new seismic responses by crosscorrelating seismic observations at different receiver locations. A first version of this principle was derived in 1968 by Claerbout, who showed that the reflection response of a horizontally layered medium can be synthesized from the autocorrelation of its transmission ...

Inspecting tidal signals observed by passive image interferometry

2023
Solid Earth is subjected to nanostrain tidal deformations caused by gravitational attraction of the Moon and Sun. This causes periodic deformations of imperceptible fractures in the shallow rock that likely result into subtle variations of seismic velocities.

Three-dimensional imaging spectrometry by fully passive interferometry

Optical Review, 2012
We have developed a method to obtain a set of spectral components of three-dimensional (3D) images for a spatially incoherent, polychromatic light source distribution by a fully passive interferometric technique. The principle of the method is based on the measurement of a five-dimensional (5D) spatial coherence function and signal processing including

Target-oriented Imaging Using Active and Passive Interferometry

78th EAGE Conference and Exhibition 2016, 2016
Target oriented imaging uses seismic interferometry to suppress overburden effects, improving resolution and image quality. Interferometry can be used to construct data that can be processed by standard imaging algorithms or it can be included as part of the depth imaging operator.

Passive Bistatic Sar Imaging and Interferometry by Using Satellite Digital TV Signal

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
In this study, we used the digital television signal broadcasted by geostationary satellite for passive bistatic synthetic aperture radar (SAR) imaging and interferometry applications. A prototype system was designed and fabricated with commercial-off-the-shelf (COTS) components.
