ABSTRACT:
A magnetic screening system uses directional gradiometers with high resolution and accuracy to measure magnetic field signatures of target objects (e.g., gun, knife, cell phone, keys) in a volume of interest. The measured signatures can be compared to signatures of known objects stored in a local database. Various mathematical processes may be used to identify or classify target object signatures. A magnetic screening system network according to embodiments of the present invention includes gradiometers, gradiometer processors, screening computers, and a management computer. The gradiometers sense target objects in a subject volume and the gradiometer processors process data obtained from the gradiometers. The screening computers process data output of the gradiometer processors and maintain local databases of signatures associated with known target objects. The management computer manages shared information for the gradiometer processors and maintains a central database of signatures associated with the known target objects.
