给出了逆Stokes公式的一种新的推导方法,以此为基础和用已知的重力场模型作为观测数据来具体分析与讨论移去恢复法的精度问题,并重点讨论了积分区域的大小和所移重力位的阶数,其结论对实际处理卫星测高数据有一定的参考价值。
The remove-restore process essentially is to replace the data outside the observed area on Earth with some known model.But in practical application,there are some problems needed to be studied when the remove-restore process is applied.For example,how to determine the integral domain and to evaluate the accuracy Firstly,this paper gives a new derivation of inverse stokes formula,and then concretely analyze and discuss the accuracy of the remove-restore method in order to research the source of error in actual computation.Combined with the accuracy problem,we focus on analyzing size of the integral domain and the number of the removed degree and obtain several useful conclusions.
