HIGH SENSITIVITY ALL METALS LOCATOR

THIS PROJECT IS DIRECTED AT ADVANCED METHODS FOR DETECTING AND LOCATING SMALL METALLIC COMPONENTS OF THE TYPE CONTAINED IN SELECTED ORDNANCE. THE WORK CALLS FOR SUBSTANTIAL INCREASES IN SENSITIVITY OVER THAT CURRENTLY PROVIDED BY CONVENTIONAL ELECTROMAGNETIC TESTERS AND METAL DETECTORS. INNOVATIVE CONFIGURATIONS OF ELECTROMAGNETIC LEAKAGE FIELD TESTS WILL BE EVALUATED, WHEREIN THE EFFECT OF TARGET EDDY CURRENT LOSSES AND/OR THE EFFECT OF THE TARGET'S MAGNETIC PROPERTIES ON A SEARCH COIL WILL BE MONITORED. SPECIALIZED PROBES WHICH COMBINE LARGE LEVELS OF FIELD INTENSITY AND PENETRATION WITH HIGH SENSITIVITY DIFFERENTIAL DETECTION SCHEMES WILL BE FABRICATED AND TESTED. THE DESIRED OBJECTIVE IS TO DEMONSTRATE FEASIBILITY OF METHODS FOR LOCATING AND CHARACTERIZING SMALL METAL OBJECTS LOCATED AT A MINIMUM OF 20 INCHES FROM THE PROBE.
