摘要
研究了水下等离子体声源的工作原理和聚焦原理,研制了小功率的实验装置,并进行了聚焦声场实验测量,从声轴和焦平面2个方向研究了声脉冲峰值压力与声场位置之间的关系,得出了聚焦声场的分布特性。研究结果初步验证了水下等离子体声源的优越性,为进一步改进这种声源,以将其应用于100km以上超远程水下通信系统打下良好的基础。
The operating and focusing principle of the underwater plasma sound source are analyzed, and lowpower test devices are developed. The measurement of the focused sound field is conducted. The relationship between the peak pressure of the sound pulse and the place of the sound filed is studied from the directions of both the sound axis and the focused plane, and the distributing characteristic of the focusing sound field is concluded. The research result preliminarily validates the superiority of the underwater plasma sound source, and lays a good foundation for the further improvement of the sound source and the application to uhra-long-range underwater communications system over 100 km.
