矢量水听器性能参数测试及分析

随着声呐探测系统性能和稳定性的不断提高,矢量水听器因能同时共点测量声波的声压和振速信息,已开始应用于声呐探测系统。为保障海上实验,设计制作了胶囊形三维压电同振式矢量水听器。依据比较法测量原理,分别在驻波声管和消声水池中,对矢量水听器的x、y、z和p通道的低频段和高频段进行了灵敏度和指向性测试。测试结果表明,该型矢量水听器灵敏度较高、指向性较好,能够满足海上实验的需求。

Parameter measurement and analysis of vector hydrophones

With the development of sonar detect system''s capacity and stability, vector hydrophone can co-locating and simultaneously measures pressure and particle velocity of acoustic field, it has been used in sonar detect system. In order to guarantee sea experiments, the tri-axial piezoelectric co-oscillation capsule vector hydrophone are designed and manufactured. According to comparison measurement principle, the sensitivities and directivities at the x, y, z and p gallery of the vector hydrophone in low and high frequency bands are measured in acoustic pipe and pool. The results of measurement indicate that the vector hydrophone''s sensitivity and directivity meet the requirement of sea experiment.
