声学多普勒剖面流速仪检测方法探讨

Discussion on the Calibration Methods for Acoustic Doppler Current Profilers

声学多普勒剖面流速仪(Acoustic Doppler Current Profiler,简称ADCP)在国内海洋调查和水文监测行业应用越来越广泛,但是作为一种计量仪器还没有行之有效的检测方法,这对仪器的使用、数据的质量控制造成很大影响。文中对国内外ADCP现场和实验室的检测方法进行了研究探讨,提出了ADCP的检测参数以及现场和实验室检测的技术难点,并对今后ADCP的检测工作给出几点建议。

Acoustic Doppler Current Profilers（ADCP） are widely applied in marine surveying and hydrological monitoring in China. However, there is no effective calibration method for ADCP, posing substantial influences on the use of the measuring instrument as well as data quality control. In this paper, the detecting methods for ADCP both in testing tank and natural waters are studied and discussed to propose the detecting parameters and technical difficulties of ADCP in the field and laboratory. This paper also provides some suggestions for the detection of ADCP in the future.
