摘　　要：地波雷达作为一种可反演海表面波浪场要素的新型海洋观测技术,其波浪参数计量校准仍然是研究难点之一。文中采用高精度载波相位差分技术,通过融合解析多星(中国北斗、美国GPS和俄罗斯GLONASS)定位信号,研究地波雷达波浪全参数高精度现场实时校准技术。现场海试结果显示:波高最大示值误差绝对值是0.12 m,波周期最大示值误差绝对值为0.4 s,波向最大示值误差绝对值为10°,均满足《海滨观测规范》要求。多星定位信号波浪校准技术为地波雷达波浪参数量值溯源提供了一种新的有效途径。HF ground wave radar(HFSWR)as a new ocean observation technology which can invert the wave field elements,the calibration of wave parameters for HFSWR is still one of the research difficulties.The high-precision Technology of real-time kinematic is studied in the paper,and through the multiple analytical satellite positioning signals(China Beidou,American GPS and Russian GLONASS),to achieve full parameters,real-time high precision and field calibration technology.By repeated marine tests,test result is accord with the specification for offshore observations,it shows that the maximum error of the wave height is 0.12 m,the maximum error of the wave period is 0.4 s;the maximum error of the wave direction is 10 degrees.Therefore,the calibration technology which is based on the fusion wave measurement by Beidou satellite provides a new and effective way in the traceability of wave parameters of HFSWR.
