Sensing and imaging systems are under increasing pressure to accommodate ever-larger and higher-dimensional data sets; ever-faster capture, sampling, and processing rates; ever-lower power consumption; ever-smaller form factor; and new sensing modali

Calibration of local seismic arrays is crucial to quantify the magnitude of local microseismic events. This is traditionally done by performing a site survey consisting of calibration shots at known locations with known strength. However, when a cali

CO2 was injected into a saline aquifer near the town of Ketzin in Germany from July 2008 to August 2013. To monitor CO2- migration close to the injection well, TNO installed a fixed 2D seismic array of 120 meters length in 2009, with 3- component (3-

This paper describes the data acquisition and processing of a 3D high resolution seismic (HRS) survey acquired off-shore Rotterdam, the Netherlands. Target of the survey was the upper 1000 meters in the vicinity of a candidate CO2 storage site. The a

TNO has carried out a high resolution 3D seismic survey off-shore Rotterdam. The new deployment concept that was tested with this survey results in high-quality 3D images of the shallow subsurface at relatively low cost, particularly in comparison wi

Implementation of geological CO2 storage requires monitoring for potential leakage, with an essential part being establishment of baseline CO2 in soil gas. CO2 concentrations and weather parameters were monitored for ∼2 years at three locations in

The variation of frequency content of a seismic trace with time carries information about the properties of the subsurface reflectivity sequence. As a result, analysis of the data in terms of the local frequency content can provide a worthwhile addit

Three-dimensional volume attribute extraction techniques have been applied to the Cenozoic succession, in a 3-D seismic data volume from the L08 block in the Dutch sector of the North Sea. Volume attribute analysis aims at the extraction of 3-D signa

We introduce a new approach to radar imaging based on the concept of compressive sensing (CS). In CS, a low-dimensional, nonadaptive, linear projection is used to acquire an efficient representation of a compressible signal directly using just a few

We present an efficient method for robustly calculating time-frequency attributes of a signal, including instantaneous mean frequency, bandwidth, kurtosis, and other moments. Most current attribute estimation techniques involve a costly intermediate
