Abstract
Methods including a Kalman filter tracking method for localizing a magnetic field source and which employs a linear perturbation method. The linear perturbation method linearizes an objective function in the neighborhood of the actual source enabling the source location to be computed in a single operation. Successive applications of the linear perturbation method lead to successive improvements in the localization result.
