【摘要】 随着卫星测高技术的发展,覆盖面更广、更密集的海洋观测系统极大地促进了大洋潮汐理论的发展。欧空局发射的CryoSat-2卫星是为专门研究冰冻圈设计的,弥补了南极大陆无法测定而造成的数据空缺。本文对来自RADS的CryoSat-2卫星数据进行了分析、提取和预处理,求出星下点轨迹在研究海域的交叉点位置;用交叉点调和分析的方法获得潮汐参数,并用来自ATG数据库的验潮站可靠参数对调和结果进行评估。更多还原

【Abstract】 With the development of satellite altimetry technology, the ocean observation system with wider coverage and more intensive has greatly promoted the development of ocean tide theory. The ESA CryoSat-2 satellite is designed specifically to study the cryosphere, filling a gap in the data created by the inability to measure the Antarctic continent. In this paper, the CryoSat-2 satellite data from RADS are analyzed, extracted and preprocessed to find the intersection point of the sub-satellite trajectory in the studied sea area. Tidal parameters are obtained by cross point harmonic analysis, and the reliable parameters of tide stations from ATG database are used to evaluate the harmonic results.更多还原
