Abstract Multichannel Analysis of Surface Waves (MASW) analysis is an efficient tool to
obtain the vertical shear-wave profile. One of the key steps in the MASW method is to …

Seismic inversion aims to reconstruct a quantitative model of the Earth subsurface, by
solving an inverse problem based on seismic measurements. There are at least three …

We propose a novel approach for removing noise from multiple reflections based on an
adaptive randomized-order empirical mode decomposition (EMD) framework. We first flatten …

基于波动方程预测的表面多次波压制方法可处理复杂地下介质的地震资料, 但计算成本较高.
基于滤波的多次波压制方法计算效率较高, 但其成功应用仅局限于一次波和多次波有明显时差 …

In the last decade, a significant shift in the marine seismic acquisition business has been
made where ocean bottom nodes gained a substantial market share from streamer cable …

The seislet transform is a waveletlike transform that analyzes seismic data by following
varying slopes of seismic events across different scales and provides a multiscale …

表面多次波是一种相干干扰, 在海洋地球物理勘探中表面多次波尤为明显.
