ADCP测流原理研究

Research on the principle of ADCP current measurement

自从提出多普勒技术测量海流原理后,海洋科技工作者一直把它作为高新技术进行研究。声学多普勒海流剖面仪(ADCP)的问世被认为是海洋测流技术的重大突破,文章介绍了ADCP窄带测流和宽带测流的原理与方法,简要阐述了窄带与宽带ADCP各自的优缺点,同时介绍了多普勒效应和多普勒时间膨胀的概念。

Since the introduction of the Doppler technique to measure the ocean current,marine scientists have been studying it as a new and high technology.The advent of Acoustic Doppler Current Profiler(ADCP)is regard as an important breakthrough of ocean current measurement technology.In this paper,the basic principle of ADCP narrowband and wideband current measurement is introduced,and the advantages and disadvantages of narrowband and wideband ADCP are briefly described,meanwhile,the concepts of Doppler effect and Doppler time dilation are introduced as well.
