In this paper, authors introduce the Doppler principle in water and analyse the feature of Doppler signal, named random nonstationary reverberation signal, furthermore discuss the designs of electronic circuits.

The research on modeling and simulation of torpedo reverberation;

The reduced rank STAP for reverberation suppression based on data smoothing;

Simulation of multi-channel moving sonar reverberation;

The reverberation time and noise level of tunnel-typed public works can be reduced by adding large amount of acoustical structure with high absorptive coefficient.

According to Sabin formula, reverberation time value of this model is calculated using AutoLISP language.

The paper proposes a nonlinear regression approach with sound level residual error least-squares for evaluating reverberation times,when reverberation decay curves are obtained by the backward integration of room impulse responses.

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.

Traditional methods to measure absorption coefficient are standing wave tube and reverberation which have some shortcomings.
