海流探测仪器与技术研究现状及展望OA北大核心CSTPCD

Accurate and real-time ocean current data serve as crucial input parameters in various domains such as marine resource development,marine resource utilization,and oceanic scientific research.Traditionally,ocean cur-rent detection instruments fall into four categories based on detection principles:mechanical,electromagnetic,acoustic Doppler,and acoustic time difference ocean current meters.Presently,novel ocean current meters incor-porating optical fiber sensing technology exist.In this paper,we provide a comprehensive review and summary of both traditional and optical fiber-based ocean current meters,covering their detection principles,advantages,dis-advantages,application areas,and current development status.Considering the future trends in the development of ocean current detection instruments,we propose a laser-generated ultrasound flow measurement method based on the continuous time difference method.Our aim is to offer insights and references for the development and research of ocean current meters,significantly contributing to the advancement of ocean exploration technology and the rapid implementation of national strategies for maritime strength.
