Abstract
An apparatus for locating a target object using parametric inversion employs a signal injector capable of injecting a signal into the target object, wherein at least a portion of the target object is buried, a magnetic field receiver, a matching processor for matching to a magnetic field received by the magnetic field receiver a parametric magnetic field distribution model corresponding to the target object and at least one other object, and a locating processor for locating the target object using parameters from the parametric magnetic field distribution model. A method for locating a target object using parametric inversion injects a signal into the target object, at least a portion of which is buried, receives a magnetic field radiated from the target object, matches to the received magnetic field a parametric magnetic field distribution model corresponding to the target object and at least one other object, and locates the target object using parameters from the parametric magnetic field distribution model.
