PARALLEL PROCESSING FOR INFRARED RADIOMETERS

CONVENTIONAL MEASUREMENT TECHNIQUES USED IN INFRARED RADIOMETRY LACK THE SPEED REQUIRED FOR MEASURING THE INFRARED SIGNATURE OF DYNAMIC TARGETS. THE SPEED OF CONVENTIONAL TECHNIQUES CAN BE INCREASED, BUT AT THE SACRIFICE OF SIGNAL-TO-NOISE PERFORMANCE. AN INFRARED RADIOMETER BASED ON PARALLEL SAMPLING AND PROCESSING TECHNIQUES CAN PROVIDE THE SAME SIGNAL-TO-NOISE PERFORMANCE AS CONVENTIONAL HIGH PERFORMANCE RADIOMETERS, WHILE SIMULTANEOUSLY PROVIDING A 64 FOLD INCREASE IN SPEED. HENCE INFRARED SIGNATURE MEASUREMENTS CAN BE ACCOMPLISHED IN 1/64TH THE TIME, WITHOUT SACRIFICE OF ACCURACY. THE PHASE I WORK PLAN INCLUDES RESEARCH ON ALL RELEVANT INFRARED RADIOMETER DESIGN OPTIONS, DEVELOPMENT OF A DETAILED DESIGN FOR A PHASE II RADIOMETER SYSTEM, DEVELOPMENT OF A NUMERICAL MODEL FOR REALISTIC PREDICTION OF RADIOMETER PERFORMANCE, AND TWO DESIGN REVIEWS AT NSWC. THROUGHOUT THE PROPOSED PHASE I RESEARCH EFFORT AND POTENTIAL PHASE II RESEARCH AND DEVELOPMENT EFFORT, WORK WILL BE CLOSELY COORDINATED WITH THE NAVY TECHNICAL STAFF TO INSURE COMPLIANCE WITH NAVY REQUIREMENTS.
