摘　　要：为探讨GNSS干涉遥感技术建立临时验潮站的可行性,基于频谱分析法和逆向建模法反演水位变化原理,提出GNSS-IR临时验潮站建立方案,并在海南三亚开展水位监测实验,评估水位反演精度和准潮汐调和分析性能。结果表明,与便携压力式潮汐仪记录水位对比,反演水位均方根误差可达5.11 cm,提取分潮振幅差值均在1 cm以内,迟角差值均在1°以内。GNSS-IR临时验潮站与便携压力式潮汐仪监测水位变化具有较好的一致性。To explore the feasibility of establishing a temporary tide gauge site using GNSS-IR technology,a plan for establishing a temporary tide gauge site is proposed based on the principles of spectral analysis and inverse modeling methods to invert water level changes.A campaign for water level monitoring is conducted in Sanya,Hainan.The performance of inversion accuracy and quasi-tidal harmonic analysis is evaluated.The results showed that,compared with the situ water level from the portable pressure tidal gauge,the root mean square error(RMSE)of the inverted water level is 5.11 cm,and the difference of extracted tidal amplitude is within 1 cm and the phase lags is within 1 degree.The water level changes monitored by the GNSS-IR temporary tide gauge and portable pressure tidal gauge have a good consistency.
