本文讨论了重力测量中的方域地形校正方案存在的不足,提出了用矩形网络的高程数据进行圆域地形校正的方案。在计算对比了方域地形校正结果(用压缩物质线和二维数值积分法计算)和圆域地形校正结果与真值之差后,认为本文所提的方案是可行的。
This paper discusses the shortcomings of the square terrain correction scheme in gravimetric measurement and proposes a scheme of the rectangular terrain correction using the elevation data of the rectangular network. After calculating and comparing the results of square topography correction (calculated by compressing material line and two-dimensional numerical integration method) and the difference between the results of true circular domain correction and the true value, the solution proposed in this paper is feasible.
