Description

technical field [0001] The invention relates to observation of ocean waves and ocean currents, in particular to a mobile observation system for surface waves and currents used for measuring dynamic parameters such as ocean surface wave fields and flow fields. Background technique [0002] Among the various ocean hydrological elements, waves have the greatest and most complex influence on human activities. Providing high-quality wave data is helpful for understanding wave characteristics, and then provides an important basis for ocean development, natural disaster prevention, ocean engineering planning, and navigation safety. [0003] Wave observation methods are mainly divided into direct observation and telemetry. The former generally directly observes the wave characteristics through direct contact with the waves through observation instruments; the latter uses photography or radio to obtain wave data. Wave buoys are unattended, have the advantages of long-term operation...

AI Technical Summary

Problems solved by technology

[0004] Traditional acceleration-type wave buoys generally observe near-shore waves in a fixed-point manner. Due to the huge body and mooring system involved, the deployment is more complicated, the cost is high, and the observation area is limited and the efficiency is low; Wave GPS, because its signal cannot penetrate water bodies, may cause data loss due to signal interruption during use, and it completely relies on external satellite information, lacking autonomy
