| Based on the theory and experiments, reverberation effects produced by underwater explosion of energy-containing materials is analyzed in this paper.The signal source model of underwater explosion is obtained through theoretic analysis. According to the basic knowledge of underwater explosion and acous t-ics. The production mechanism of underwater explosion is also analyzed on the basis of dispersion phenomenon. Acoustic model to describing the underwater reverberat i-on is set up and the computation method of volume reverberation is inferred. Two methods of enhancing the underwater reverberation effects are proposed. These methods of enhancing the reverberation effects are vali-dated according to the analysis of underwater experi m-ent data and the betterment methods are also proposed. Besides, the signal-processing software is also written to computer the underwater reverberation and to analyze the acoustic character of tapped charging. |
