水下等离子体定向辐射声源干扰特性研究
Interference Characteristics of Underwater Plasma Directional Radiation Sound Source
摘要
Abstract
As a new technology ,underwater shockwave has the characteristics of high sound level ,narrow pulse width and wide frequency band .The underwater acoustic interference principles and demand analysis of sound source are elabora-ted ,the underwater plasma directional radiation sound source generation mechanism ,bunching up principles and the corre-sponding generation system are introduced ,the remote propagation experiment of underwater shockwave is carried out in the lake ,the waveforms and the corresponding power spectrums are also analyzed .The results show that the maximum source level of the plasma sound source is high and the frequency band is wide ,which has a good application prospect in underwater acoustic countermeasure .关键词
