Self-constrained Inversion of Potential Fields

We propose a constrained inversion procedure based on a priori information derived exclusively from the potential field data themselves (self-constrained inversion). To set up effective constraints, we utilize two source parameters, namely the structural index N and the position of the source body edges, both estimated through analysis of the field itself. With some synthetic examples, we show that this information, incorporated in the objective function as depth and horizontal weighting functions, is enough to obtain rather accurate and realistic magnetization models.
