Locating stationary magnetic objects

CCDC ARL

A technique for locating stationary magnetic objects comprises placing magnetic sensors on a movable platform; for each sensor, measuring a total magnetic field signal in an area of detection; using the sensors to identify a line upon which a target stationary magnetic object is located; and fixing a location of the object by moving the platform in substantially straight lines until the object is detected by at least two of the sensors; using the measured signals to determine a first path on which the object lies; positioning the sensors so that a line connecting two of the sensors intersects the first path on which the object lies; moving the platform along a second path substantially parallel to the first path; recording two positions at which at least two of the sensors detect a maximum total magnetic field signal from the object; and identifying a third path through the two positions.
