Abstract

With regard to the shipmountedADCP (Acoustic Doppler Current Profiler), which has been widely used for current measurement since 1980's, a type using four acoustic beams transmitted downwardfrom a vessel (four-beamtype) is major internationally. In Japan, however, in addition to the four-beam type, a type using three acousticbeams (three-beamtype) is also popular,but is not well documented in terms of technical issues in comparison with the four-beam type. Although the instrumental principle of the two types does not have big differences, data processing formulations are a little different. The presentstudyprovides a generaldescription of current measurement with three-beam type ADCP, including data processing formulations, error sources, and practical methods of error correction.
