中心固定组合矢量水听器结构变化形式研究

Study on Structural Changed of Central Fixed Combination Vector Hydrophone

给出中心固定组合矢量水听器结构变化形式模型及工作原理;建立其振速水听器的等效电路模型,推导接收响应表达式,并与中心固定组合矢量水听器进行对比分析。结果表明:结构变化形式水听器具有与中心固定组合矢量水听器相同的尺寸优势与安装优势,且其工作频率低,丰富了结构形式,调整了其工作频率范围,使得中心固定组合矢量水听器拥有更广泛的应用范围。

The structure and working principle of the central fixed combination vector hydrophone structure are described.The equivalent circuit model of the velocity hydrophone is established,and the receiving response expression is deduced.It is compared with the traditional frame suspended velocity hydrophone and the central fixed combination vector hydrophone.The results show that the structure-changed hydrophone has the same size and installation advantages as the fixed central combined vector hydrophone,and its working frequency is low,which enriches the structure and adjusts its working frequency model.The central fixed combina⁃tion vector hydrophone has a wider application area.
