一、概述岸用声学测波仪是一种定时或随时自动记录近岸海浪健高及周期的水文仪器。可供沿海各台站长期观测波浪要素用,亦可在港工建筑和水下作业等方面做为波浪观测仪器。该仪器以图示形式记录波浪,在仪器机箱后面板上附有一个数码输出插座,以便用数字计算机进行数据处理。本仪器的基本工作原理为声纳测距。超声波换能器用支架固定于被测点的海底,发射信号与回波信号通过水下电缆传递;电子线路与记录部分都放在岸边观察室内,可以随时获得
I. Overview Shore Acoustic Wavemeter is a kind of timing or at any time automatically record nearshore wave height and cycle hydrological instruments. It can be used for long-term observation of wave elements at various stations along the coast and also as a wave observation instrument in port construction and underwater operations. The instrument records waveforms in graphical form with a digital output socket attached to the rear panel of the instrument chassis for data processing with a digital computer. The basic working principle of this instrument is sonar ranging. The ultrasonic transducer is fixed to the seabed of the measured point by a bracket, and the transmitted signal and the echo signal are transmitted through the underwater cable. The electronic circuit and the recorded part are placed on the shore observation room and can be obtained at any time
