We review the equations for correlation-based redatuming methods. A correlation-based
redatuming method uses natural-phase information in the data to time shift the weighted …

Near-surface site characterization is of great significance in the fields of geotechnical
engineering and resource exploration. In this paper, we propose a near-surface site …

Classical algorithms used for traveltime tomography are not necessarily well suited for
handling very large seismic data sets or for taking advantage of current supercomputers …

We develop a waveform-tomography method for estimating the velocity distribution that
minimizes the waveform misfit between the predicted and observed early arrivals in space …

摘要根据地震波传播的有限频理论, 对于某个特定震相的观测信息, 不仅射线路径上的点对该
信息具有影响, 射线领域上的其他点对接收信息也具有影响, 这种影响可以用核函数来表达 …

Full waveform inversion (FWI) is a promising technique for inverting a high-resolution
subsurface velocity model. The success of FWI highly depends on a fairly well initial velocity …

在地表一致性模型的基础上提出一种可适用于宽线剖面, 弯曲测线, 传统的二维和目前广泛使用
的三维地震观测. 在地形及近地表低降速带地质结构复杂的探区, 低降速带厚度及速度估算的 …

A combination of geophysical methods has been used for the characterisation of a rockslide
area, located in the Graie Alps, NW of Italy, where the construction of a roadway tunnel has …

Target-oriented inversion (TOI) is an approach aimed at enhancing the ability of full-
waveform inversion (FWI) to achieve a high-resolution delineation of a reservoir. FWI has …

Correctly interpreting phase events thanks to data processing techniques based on
correlation or deconvolution has been the focus of numerous studies in the field of high …
