多源重力场信息融合处理方法

Fusion Methods of Multi-Source Gravity Field Information

针对如何有效融合陆海交界区域不同分辨率的多源重力数据,本文重点研究了最小二乘配置、多分辨率最小二乘配置和点质量建模理论的数据融合处理方法。通过对实验区的多源观测数据融合处理,结果表明,3种融合方法反演的陆地重力异常数据的外符合精度在3×10-5m.s-2左右。多分辨率最小二乘配置和基于点质量理论的多源重力信息融合处理方法,能够达到有效融合各种分辨率数据的目的。

In this article,the different resolution of the multi-source gravity data among border regional between the land and the ocean were blended which was based on the least squares collocation,the multi-resolution with least squares collocation and the theory of point mass model.The result showed that the fusion accuracy of three methods was about 3×10-5m·s-2 and the theory of point mass model and the multi-resolution with least squares collocation reached the target of effective fusion of the several resolution data.
