Abstract
In the complex magnetic anomalies under undulating terrain, multiple source superposition and significant noise conditions, the “noise avoidance inversion” depends on three experiments. 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.
