Experimental Research on the Feature Extraction of Underwater Transient Signal

Abstract:

After the aerial object enters the water, splash sound forms. It composes of water entry pulse signal, quiet interval, and bubbles fluctuant signal. To extract the characteristics of the splash sound, characteristics of the three parts of the signal are analyzed in theoretically. And then experimental research is done, in which five different targets are adopted to be launched under different conditions. Comparing with the results of different conditions, we draw some conclusions which coincide with the theoretical analysis.
