Research on the signal modeling method for sea bottom reverberation based on ray theory

Therefore,an algorithm of scattering cell division for bottom interface side-scattering in bistatic sonar is proposed and the bottom reverberation model in bistatic sonar based on SSA scattering strength is developed.

Research on space correlation characteristic of horizontal bistatic seafloor reverberation signals

Focus on the completion of multibeam seafloor reverberation simulation so tha

Based on the representation of impulsive sound propagation with the moving source and receiver,a seafloor reverberation signal model is derived from the monostatic sonar moving horizontally in horizontally stratified oceans.

Direct arrival , ghost wave and water column reverberation on sea-bottom multi-component data.;

OBC dual-receiver is a new-developed exploration technique in the late eighties of last century, which is mainly used to suppress "water column reverberation" interference appeared between sea bottom and sea level that resulted in effectively improving S/N ratio of seismic data.

Nonlinear prediction of underwater reverberation based on a Volterra adaptive filter;

A new method for feature extraction from underwater reverberations based on phase space reconstruction;
