卫星测高中的垂线偏差法

Vertical Deflection Theorem of Satellite Altimetry

卫星测高中的垂线偏差法是当前利用卫星测高技术研究海洋重力场的最优方法,包括利用卫星测高数据计算垂线偏差和利用该垂线偏差确定海洋重力场两部分。研究了Sandwell、Olgiati、Hwang测高垂线偏差的计算方法和Molodenskii、Hwang利用测高垂线偏差确定海洋重力场的基本原理,分析比较了上述方法的异同,为科学地利用卫星测高资料反演海洋重力场提供理论依据。

The vertical deflection theorem of satellite altimetry has become the optimal way to research the marine gravity field, which includes computing the vertical deflections from the altimeter data and determining the marine gravity field from the vertical deflections, Three main approaches of computing the vertical deflections from the altimeter data presented by Sandwell, Olgiati and Hwang, respectively, have been studied, And two theorems of determining the marine gravity field from the vertical defelctions proposed by Molodenskii and Hwang, respectively, are compared, The paper severs for determining scientifically the marine gravity field from the altimeter data,
