摘　　要：波向是波浪三要素之一,常利用磁力式或GNSS(Global Navigation Satellite System)式波向传感器获得,目前我国沿海有数百台处于工作状态的波向传感器。为获取准确可靠的波向数据,需对波向传感器开展校准工作,波向校准技术仍是研究难点之一。开展了波向传感器的岸基量值传递计量技术工作研究。设计机械运转平台,配置电气部件,编写控制程序,研建一套波向新计量校准系统;编写实验方案,细化实验流程,开展实验测试研究工作,获得实验数据。分析处理实验数据,获得最大示值误差、扩展不确定度等实验结果。实验结果显示,磁力式和GNSS式波向传感器最大示值误差分别为6°和4°,GNSS式传感器具有较大技术优势,计量校准扩展不确定度为3.3°。结果表明校准方法符合国家标准要求,方案合理,技术可行。Wave direction is one of the three elements of the wave,often acquired by using magnetic or GNSS(Global Navigation Satel-lite System)type wave direction sensor.There are hundreds of working wave direction sensors along the coast of our country.In order to obtain accurate and reliable wave direction data,it is necessary to calibrate the wave direction sensor,and the wave direction calibration technology is still one of the research difficulties.Research on the technology of shore-based value transfer measurement for wave trans-ducers is carried out.The mechanical running platform is designed,the electrical components are configured,the control program is writ-ten,and a new wave direction measurement and calibration system is developed.The experimental scheme is written,the experimental process is refined,experimental testing and research work are carried out,and experimental data are obtained.The experimental data are analyzed and processed,and the experimental results such as maximum indication error and extended uncertainty are obtained,showed that the maximum indication errors of the magnetic and GNSS wave direction sensors are 6°and 4°respectively.The GNSS sensor has great technical advantages and the extended uncertainty of metrological calibration is 3.3°.The results show that the calibration method meets the requirements of national standard,the scheme is reasonable and the technique is feasible.
