摘要
扼要综述了现有的七种水下声源产生技术,包括炸药爆炸声源、电声换能器声源、参量阵声源、流体动力式声源、电磁式声源、激光声源和等离子体声源。分析了这些声源的发声机理,结合其性能特点阐述了在实际中的不同应用,并对等离子体声源的机理、特点和实际应用进行了重点分析。列表归纳总结了各种水下声源的原理、主要性能和应用范围,为水下声源的应用拓展提供了依据。
Seven types of underwater sound source techniques are ummarized, which include the explosive sound source, the electroacoustic transducer sound source,the parametric array sound source, the hydrokinetic sound source, the electro- magnetic sound source, the laser sound source and the plasma sound source. Their generating mechanisms are analyzed and compared in terms of their respective characteristics. Moreover, the mechanisms, features and applications of the plasma sound source are emphasized. The principia,the capabilities and the applications of all the 7 types of sources are finally listed in table form, providing reference for wide applications of underwater sound sources.
