Abstract
A three-dimensional real-time differential gradiometric magnetometer (DGM) array, system and method of use. The DGM exploits differential and gradiometric parametrics of an induced magnetic field anomaly surrounding an object interacting with an applied magnetic field. The DGM integrates differential magnetic field measurement with gradiometric magnetic field measurement into a single system. The DGM detects, locates and maps objects, while simultaneously measuring the distance between the DGM detection array and the object, axial orientation, apparent magnetic mass and magnetic moment. The DGM employs a signal processing technique to nullify source noise from the earth'"'"'s magnetic field, external radio frequency transmissions and electromagnetic noise. A linear geometric architecture comprising a plurality of magnetometers forming the array enables the DGM to collect information directly in the spatial domain. The DGM is capable of capturing the complete field anomaly contour in three dimensions while the array traverses over, under or adjacent to an object.
