Interpretation of magnetic gradient tensor for automatic locating a dipole source

Summary

In this paper, I propose the algorithm that the location of a magnetic dipole can be detected from the magnetic gradient tensor. I derive the location vector of a vertically magnetizated dipole from magnetic gradient tensor. Deficit of magnetic moment of magnetic dipole makes the induced location information incomplete. However if the observation of magnetic gradient tensor would be collected on one more points, the algorithm is able to point the location of magnetic dipole by clustering the solution of the proposed method. For example, I show that magnetic gradient tensor can be converted as the source location successively by picking common solution area in synthetic case of borehole observation.
