摘要
利用回声信号探测无声目标的原理,测量信号往返所需时间与在水中超声波声速的乘积,就可以确定目标所处的位置。根据该原理来探测海底微地形的高程数据,为此对适合于深海环境下工作的超声波换能器参数进行了理论分析与设计计算,该参数将为海底微地形探测系统提供技术依据。
According to the principles of underwater sound, it measures time of sound out and home and the distance has already been closely calculated by means of product of time and sound velocity under water. However, none of ultrasonic transducers suits to deep-sea circumstance. In order to manufacture the ultrasonic transducer, it is analysed and designed. These data offer reference to the measuring system of tiny landform.
