Research on Measurement and Detection Technology of Radar Tidal Gauge
The radar tidal gauge is small and light,easy to install and maintain,and has been gradually applied to the field of Marine hydrological observation.A detection technology of radar tidal gauge based on water tower is proposed.The detection items,detection methods and data processing process are defined and the factors affecting the accuracy of the test results were emphatically analyzed The test results show that the detection results of guided wave radar tide gauge are better,and the maximum error is±3 mm.The tide height error trend of forward and reverse stroke of open radar tidal gauge is basically the same,but the errors deviation of low water level and high water level both are±11 mm,and the main reasons are further analyzed.The return error results of the two types of gauges are better.The research content fills the detection gap of this kind of tidal level observation instrument and plays an important role in guiding and promoting the development of measurement technology of radar tide gauge and the formulation of relevant national metrological technical specifications.
