摘要
描述了利用Ｔ／Ｐ卫星测高数据确定中国海域及其邻海的海面地形。处理了Ｔ／Ｐ５９～８２周（Ｃｙｃｌｅ）１９９４年第８３ｄ～３１１ｄ的数据，将５９～８２周数据分成两部分分别估计海面高，并分析了海面高变化。结果与Ｂａｓｉｃ和Ｒａｐｐ１９９２年确定的海面高作了比较。利用Ｓｈｅｐａｒｄ曲面拟合方法给出了３０′×３０′平均海面高结果，分别以ＯＳＵ９１和ＷＤＭ９４地球重力场模型作为参考重力场，计算了相应的３０′×３０′平均海面地形。
This paper deals with the determination of the sea level height and seasurface topography in the china sea and neighbour by TOPOX/POSEIDON (T/P)satellite altimeter data. The data of T/P 59～82 'cycles covering 83th～ 311thdays in1994 are processed. The data of 59～82 cycles are divided into two parts,which haverespectively been used to estimate the sea level height and to analyze the sea levelchanges. The obtained results are compared with the sea level heights estimated byBasic and Rapp in 1992 Using the combined solutions of Geos - 3, Seasat, Geosat,and ETOPOSU bathymeter data. Results of the 30' × 30' mean sea level heights areobtained by the Shepard curve fitting method. Taking respectively the OSU 91 andthe WDM 94 earth gravity field models as the reference gravith field,the 30' × 30'mean sea surface topography is computed.
