Reverberation generated by sequential underwater explosions

Abstract

In order to obtain long-time reverberation, an innovative experiment is operated, using a sequence of explosions with a interval time. The relationship between reverberation generated by single explosion and a sequence of explosions is discussed. The data are obtained from the experiment, then analyzed with method of wavelet transform, conclusion is obtained that power generated by sequence of explosions with different interval time spreads uniformly at low frequency range, unequally at high frequency range.
