Abstract

Abstract

With the accumulation of measured magnetic data, it is becoming urgent to use these data efficiently. Previous studies have shown that it is difficult to meet the accuracy requirement for solving geological problems by using the measured data from a single observation method. Because of the limitations and differences in resolution, accuracy, elevation and range of magnetic data obtained by various methods, single dataset can only effectively reflect the information over a certain range of wavelength of magnetic field. An effective way to solve this problem is the fusion of data. Therefore, based on the equivalent source method, a multi-layer equivalent source technology is proposed in this paper, which can be applied to the fusion of ground and airborne magnetic data to improve the accuracy of interpolation, continuation, extension, transformation, et al. According to the spectral characteristics of observation data, three-layer equivalent sources at different depths are used to fit the measured data. Compared with the traditional single-layer equivalent source method, it can reduce the blindness for setting equivalent sources, and improve the ordering and structural performance for allotting observation information into equivalent sources. Synthetic experiment shows that the three-layer model has higher computational accuracy, and data fusion can significantly improve each dataset. Finally, the method is applied to the fusion of ground and airborne magnetic data in Jinniu basin, Hubei, and abundant magnetic data with regular distribution on a plane are obtained.
