| Abstract: | We expand the 3D correlation imaging method of gravity and gravity gradiometry data into magnetic exploration. We derive and propose the 3D correlation imaging method for magnetic anomaly △T data, and also propose the algorithm of the 3D correlation imaging based on entropy filter for anomaly separation, which can be used to improve the resolution of the imaging. The test on the magnetic anomaly △T clata of synthesized multiple rectangular prisms model and the raw magnetic data show that, the method can image the space extended states and the distribution of equivalent magnetism of geological anomalous bodies with high resolution both longitudinally and transversely. |
