【摘要】 利用测高卫星的冻结轨道特征计算了正常点轨迹,利用三次B样条函数和Stacking技术内插计算了T/P、ERS-1/2和Geosat测高数据在正常点的平均海面高,改善了测高数据的精度和分辨率.最后,利用正常点上的平均海面高反演了多种分辨率的海域重力异常,其中所反演的海域重力异常的标准差为mGal级.更多还原

【Abstract】 The normal points of the altimetry satellite are computed according to the frozen orbit of the altimetry satellite. The cubic B\|sample functions and the Stacking technique are applied to determine the mean SSHs at the normal points from the altimeter data of T/P, ERS\|1/2 and Geosat satellite, which improves the accuracy and resolution of the altimeter data. Finally, multi\|resolution marine gravity anomalies are determined from the mean SSH, and the STD of the marine gravity anomalies is mGal. 更多还原
