OF NUCLEAR STORAGE FACILITIES

SINCE 1975, THE USAF HAS DEVELOPED THROUGH ITS FUZING BRANCH, EGLIN AFB, A NEW CLASS OF PROXIMITY DETECTORS KNOWN AS BASEBAND REFLECTOMETER (BAR) SYSTEMS. IN ADDITION TO HAVING EXCELLENT RESOLUTION (E.G.LESS THAN A FOOT), BAR SYSTEMS HAVE BEEN MADE IMMUNE TO MANY FORMS OF JAMMING AND HAVE BEEN USED AS ALTIMETERS IN TARGET ACTIVATED MUNITIONS(TAM) APPLICATIONS AS WELL AS SENSORS FOR PROXIMITY FUZES. BECAUSE OF THE WIDE ANGULAR COVERAGE INTRINSIC IN BAR OR CARRIER-FREE SHORT PULSE TRANSIENT) SYSTEMS, THE AF INVESTIGATED, AS PART OF ITS FUZING PROGRAM, ITS APPLICATION TO AREA SURVEILLANCE FOR PROTECTING PARKED AIRCRAFT CARRYING NUCLEAR WEAPONS. PRELIMINARY TESTS WERE EXTREMELY ENCOURAGING AND RECOMMENDATIONS WERE MADE TO CONTINUE RESEARCH. THE AF SUGGESTED THAT THE DNA SHOULD BE APPRISED OF THE TECHNIQUE BECAUSE OF THEIR CHARTER TO DO RESEARCH IN SECURITY SYSTEM APPLICATIONS. THE PURPOSE OF THE PROPOSAL PROGRAM IS TO CONTINUE THE RESEARCH FOR THE PURPOSE OF DEVELOPING A NEW CLASS OF COVERT, RANGE GATED SECURITY FENCE, FOR AREA COVERAGE AGAINST HUMAN INTRUDERS. THE BAR SENSOR APPEARS TO OFFER SIGNIFICANT IMPROVEMENT OVER CONVENTIONAL RADAR TECHNIQUES FOR DISTINGUISHING, FOR EXAMPLE, WIND BLOWN TREES FROM HUMAN TARGETS. EXPERIMENTAL EVIDENCE SUPPORTING THIS CONCLUSION IS PRESENTED.
