The displacement experiment accurately solves the prediction problem of the form of the target magnetic source, finds the matching relationship with the maximum thickness of the target magnetic source, and the noise change experiment demonstrates the reliability of the noise avoidance inversion. It can be seen that “noise avoidance inversion” creates a “chaotic image back to true” inversion route for complex magnetic anomalies. Noise avoidance inversion of multi-source superimposed complex magnetic anomalies in Erhai Lake is an example.展开更多

Based on the theory of differentiating different forms of magnetic sources by integral magnetic anomaly curves, a unified expression for calculating magnetic fields of different magnetic sources under undulating terrain conditions is given, and the triangular system plate interpretation method is used to identify the magnetic fields of different magnetic sources. The calculus parameter basis for the classification of unknown magnetic source morphology and the method technology for determining the magnetic source spatial morphology are confirmed. The example shows that the application of the calculus triangulation method to the magnetic source morphological system inversion has a good prospect.展开更多
