Curved-grid kriging gridding method and its application to near-station terrain correction in gravity measurement
摘要
Abstract
In this paper,a high⁃accuracy and strong stability near⁃zone terrain correction method is discussed.Firstly,combining Krig⁃ing gridding method with curved⁃grid computation technology,a Curved⁃Grid Kriging Gridding Method( short for CGKG⁃M) and its ex⁃tending edge techniques are implemented to realize data⁃gridding in circle area;Next, this method is used to compute near⁃zone terrain correction value and realize the gravity measurement near⁃zone terrain correction value's computation which contains any angles and circles.Finally,some modeling tests,real data computation and error analysis of this method are carried out.The research result has shown that CGKG⁃M near⁃zone terrain correction value computation method has some characteristics,such as high computa⁃tion accuracy,strong stability and flexibility.It is a simple,efficient and fast method for near⁃zone terrain correction value computation which matches the measurement data form of GTCS⁃1 gravity measurement near⁃station correction instrument.关键词
