摘　　要：卫星重磁观测数据覆盖范围广、更新周期快是现代地球物理中重要的数据类型之一.随着卫星重磁观测技术的不断发展,卫星重磁观测数据的精度和分辨率得到了大幅提高,被广泛的应用于探索地球、月球、火星等天体内部物质分布、结构、构造等地学问题的研究.在研究过程中,对卫星重磁数据选择合适的处理和反演方法是后续能否进行精确分析解释的重要前提.基于球坐标系下的卫星重磁数据解算、正、反演方法为大尺度地学问题的球面研究为更贴近于实际地质情况提供了方法技术支持.本文针对卫星重磁数据的曲面数据和大尺度应用研究的特点,对近年来提出的球坐标系下Tesseroid单元体的正、反演方法进行了较为全面的阐述.可为国内同行深入了解卫星重磁数据在球坐标系下的研究现状和开展进一步的研究提供参考,促进卫星重磁数据在我国地球系统科学领域中发挥更大作用.It is one of the important data types in modern geophysics that satellite gravity and magnetic observation data cover a wide range and update cycle quickly.With the continuous development of satellite gravity and magnetic observation technology,the precision and resolution of satellite gravity and magnetic observation data have been greatly improved.They are widely used to explore the distribution,deep structure,and other earth science problems in the inner planet.In the research process,the selection of appropriate processing and inversion methods for satellite gravity and magnetic data is an essential prerequisite for accurate subsequent analysis and interpretation.The calculation,forward,and inversion methods of satellite gravity and magnetic data based on spherical coordinate systems provide technical support for the spherical research of earth science problems,and the analysis and interpretation based on spherical results will be more close to the actual geological conditions.In view of the characteristics of surface data and large-scale application research of satellite gravity and magnetic data,this paper gives a full description of the methods for calculation,forward and inversion of satellite gravity and magnetic data in the spherical coordinate system proposed in recent years.It provides a reference for domestic counterparts to understand the research status of satellite gravity and magnetic data in the field of geophysics and carry out further research.It promotes the satellite gravity and magnetic data to play a greater role in earth system science.
