A geophysical integration inversion me thod based on data fusion
一种基于数据融合的地球物理数据联合反演方法

The geophysical inversion can be regarded as an understanding or interpretation of geophysical property on the basis of the observed data, while the inversion of multiple geophysical data can be regarded as a fusion of multiple sensor data. The fuzzy features of geophysical data were analyzed. The characteristic data of different physical meaning and scales, and the knowledge of geology and geophysics in the studied area are combined using the method of a uniform linguistic defuzzification. The method integrates the geophysical expert knowledge, and carried out data fusion using fuzzy inferential network. The method makes full use of all information of manifold geophysical data, avoiding the complicated calculation in linear joint inversion, and provides a new idea for the geophysical inversion about the data fusion point of view. It was proved to be effective through modeling test and application in Guyuan.
