摘　　要：声纳技术是人类探索海洋的主要手段,而水声传感器是声纳装置的重要组成部分。水声传感器分为标量和矢量水声传感器。矢量传感器可以弥补标量传感器获取声场信息不完整的不足,可以实现对水中声压和介质振速的精确测量从而确定目标方位等。主要对速度型矢量水声传感器的频率响应特性进行了研究,讨论高保真和高增益下速度型水声振幅模型、响应比及频率响应特性,提出频响设计原则,最后概括速度型水声传感器的应用。水声传感器是水下探测、定位和通信的重要手段。研究有助于开发高灵敏度和更好低频特性的速度型水声传感器,从而极大提升传统水声传感器的作用距离。远声场传感器的研制,提升诸如潜艇、UUV等水下目标的探测距离,将有利于从根本改变目前我国水声探测网络的格局,具有重要军事意义。Sonar technology is the main method of the ocean exploration,and underwater acoustic sensor is an important part of sonar equipment.Underwater acoustic sensors are divided into scalar and vector underwater acoustic sensors.The vector sensor can make up for the incomplete sound field information obtained by the scalar sensor,and can accurately measure the sound pres-sure in water and the vibration velocity to determine the target orientation,etc.This paper mainly studies the frequency response characteristics of velocity vector underwater acoustic sensor,discusses the amplitude model,response ratio and frequency re-sponse characteristics of velocity type underwater acoustic sensor under high fidelity and high gain,puts forward the design prin-ciples of frequency response,and finally summarizes the application of velocity underwater acoustic sensor.Underwater acoustic sensor is an important means of underwater detection,positioning and communication.The research helps to the development of velocity acoustic sensors with high sensitivity and better low frequency characteristics,so as to greatly improve the operating range of traditional acoustic sensors.The development of far-sound-field sensor helps to improve the detection range of underwa-ter targets such as submarines and UUV,which will fundamentally change the pattern of China's underwater acoustic detection networkwith important military significance.
