Deghosting, Demultiple, and Deblurring in Controlled-Source Seismic Interferometry
International Journal of Geophysics, 2011 With controlled-source seismic interferometry we aim to redatum sources to downhole receiver locations without requiring a velocity model. Interferometry is generally based on a source integral over cross-correlation (CC) pairs of full, perturbed (time ...

Discovery of two new bright magnetic B stars: i Car and Atlas
, 2015 The BRITE (BRIght Target Explorer) constellation of nano-satellites performs seismology of bright stars via high precision photometry. In this context, we initiated a high resolution, high signal-to-noise, high sensitivity, spectropolarimetric survey of ...

Groundwater Monitoring with Passive Seismic Interferometry
Journal of Water Resource and Protection, 2017 Passive seismic interferometry takes advantage of natural ambient seismic noise generated by the wind, the storms and the human activities (e.g. cars, trains and hereafter pumps) to recover the slight variations of the seismic wave velocity induced by changes in the groundwater level.

Uncertainty quantification in seismic interferometry
, 2022 It is a well-established principle that cross-correlating wavefield observations at different receiver locations yields new responses that, under certain conditions, provide a useful estimate of the Green's function between the receiver locations. This principle, known as wavefield interferometry, is a powerful technique that transforms previously ...

Seismic interferometry for in-mine exploration
, 2022 Im Zuge des Forschungsprojektes "Seismic Imaging Techniques for Mineral Exploration" wurde die Anwendung von passiver seismischer Interferometrie (PSI) in untertägigen Strecken und dessen Eignung für die Mineralexploration getestet. Zu Validierungszecken wurde PSI mit der 3D-Bohrlochradartechnologie und einer aktiven seismischen Messung verglichen. Die

L’interferometria SAR satellitare per la misura delle deformazioni superficiali
GEOmedia, 2012 La tecnica interferometrica, basata sull’elaborazione coerente della fase del ritorno del segnale radar dalla superficie terrestre, ha reso il telerilevamento radar uno strumento di analisi quantitativa in molteplici campi applicativi quali cartografia,

Proposed satellite laser ranging and very long baseline interferometry sites for crustal dynamics investigations [PDF]
Recommendations are presented for a global network of 125 sites for geodetic measurements by satellite laser ranging and very long baseline interferometry. The sites were proposed on the basis of existing facilities and scientific value for investigation

Extracting information from noise [PDF]
, 2010 Seismic waves created by sources such as wind, the ocean and human activity propagate inside the Earth all the time. Such waves are often regarded as ‘noise’ by seismologists, however, they travel through the Earth in exactly the same way as those ...
