ABSTRACT:
A target's magnetic dipole includes both a permanent component and an induced component that is caused by the interaction of the target at a given heading with the ambient magnetic field. In order to accurately classify targets, a library of characterization matrices is built for a plurality of candidate targets. The matrices characterize what the magnetic dipoles would be in a given ambient magnetic field at a particular heading. In practice, some localization algorithm is used to provide a target's magnetic dipole and heading. Magnetic dipoles for each of the candidate targets are predicted using the target's heading, the ambient magnetic field, and the characterization matrices. The target is then classified as the candidate target(s) providing the best match to the target's measured magnetic dipole.
