Surface wave extracting from reflection seismic data and structure imaging of shallow seafloor

摘要

This paper takes a set of OBC data collected by ocean bottom cable in an offshore district of pohai in China as example to separate surface wave.Multi-resolution analysis and τ-p transform are used respectively in the extracting.The effect of them are compared and analyzed in detail.Then the dispersion curves obtained from the surface wave data are used in imaging and inversion of shallow seafloor structure.And a good result is obtained.
