CLOSED LOOP MAGNETIC SIGNATURE REDUCTION SYSTEM

GEO-CENTERS, INC. PROPOSES TO DESIGN, DEVELOP AND TEST AN ACTIVE, 3-AXIS MAGNETIC SIGNATURE REDUCTION SYSTEM CAPABLE OF CANCELING MAGNETIC SIGNATURES OF MECHANICAL/ELECTRICAL SYSTEMS TO LEVELS BELOW THAT SEEN BY MAGNETIC INFLUENCE MINES AT DISTANCES OF TENS OF FEET. THE ULTIMATE SYSTEM WILL INVOLVE NUMBERS OF INDIVIDUAL REDUCTION SYSTEMS CONSISTING OF THREE SINGLE AXIS MAGNETIC SENSOR PAIRS COUPLED VIA A DYNAMIC FEEDBACK CIRCUIT TO 3 FIELD NULLING COIL PARIS ENABLING THE GENERATION OF A REAL TIME MAGNETIC DIPOLE WITH VARIABLE POSITION, ORIENTATION, AND INTENSITY WHICH WILL EXACTLY CANCEL THE MAGNETIC SOURCE DIPOLE. EACH MAGNETIC SENSOR/FEEDBACK CIRCUIT WILL BE INTERFACED TO A 3-AXIS AMBIENT EARTH FIELD MAGNETOMETER ENSURING A DYNAMIC AND ACCURATE NULLING FIELD ALLOWING A MINESWEEPER TO TRAVEL MAGNETICALLY UNDETECTED. THE PHASE I SBIR PROGRAM WILL ANALYTICALLY DETERMINE AND EXPERIMENTALLY DEMONSTRATE THE ABILITY OF THIS CLOSED LOOP MAGNETIC SILENCING CONCEPT TO CANCEL MAGNETIC SOURCE MOMENTS AT NEAR DISTANCES IN THE LABORATORY. DATA COLLECTED FROM AN ISOLATED SYSTEM AND IN PROXIMITY TO A SECOND SYSTEM WILL DEMONSTRATE THE CAPABILITY OF THE TECHNOLOGY FOR MULTI-SOURCE SIGNATURE REDUCTION AND ANALYTIC CALCULATIONS WILL BE PERFORMED TO DETERMINE THE EFFECTS OF HIGHER ORDER SOURCE FIELDS.
