A deterministic algorithm for experimental design applied to tomographic and microseismic monitoring surveys [PDF]

, 2004
SUMMARY Most general experimental design algorithms are either: (i) stochastic and hence give different designs each time they are run with finite computing power, or (ii) deterministic but converge to results that depend on an initial or reference ...

Shear-Wave Tomography Using Ocean Ambient Noise with Interference

Remote Sensing, 2020
Ambient noise carries abundant subsurface structure information and attracts ever-increasing attention in the past decades. However, there are lots of interference factors in the ambient noise in the real world, making the noise difficult to be utilized ...

Methodological advances in seismic noise imaging of the Alpine area

Comptes Rendus. Géoscience
Methodological advances in seismic tomography are often driven by the quality of data sets. The dense and homogeneous spatial coverage of the AlpArray seismic network, including hundreds of permanent and temporary broadband stations, has motivated a ...

An Envelope Travel-Time Objective Function for Reducing Source–Velocity Trade-Offs in Wave-Equation Tomography

Remote Sensing, 2022
In conventional cross-correlation (CC)-based wave-equation travel-time tomography, wrong source wavelets can result in inaccurate velocity inversion results, which is known as the source–velocity trade-off.
