ACT PATTERN MATCHING SYSTEM

IN VERY DENSE ELECTROMAGNETIC SIGNAL ENVIRONMENTS, A FAST ANALOG PREPROCESSOR MAY BE OF SIGNIFICANT VALUE IN REDUCING THE BURDEN OF A/D CONVERTERS AND DIGITAL PROCESSORS AND MAY SUBSTANTIALLY REDUCE RESPONSE TIME IN EW SYSTEMS. THIS PROPOSAL SEEKS TO DESIGN AND EVALUATE AN ANALOG PATTERN-MATCHING SYSTEM BASED ON THE EMERGING TECHNOLOGY OF ACOUSTIC CHARGE TRANSPORT (ACT). THIS SYSTEM MAY BE USED TO SCREEN SIGNALS FROM A MULTICHANNEL ESM RECEIVER PRIOR TO A/D CONVERSION, THEREBY REDUCING THE DIGITAL PROCESSING BURDEN BY 2 TO 3 ORDERS OF MAGNITUDE. THE PROPOSED SYSTEM USED GAAS IC ANALOG PROCESSORS WHICH ARE WELL-SUITED TO ON-BOARD ESM SYSTEMS. THE PROPOSED CONCEPT DEMONSTRATION PROGRAM WILL BE ACCOMPLISHED IN 2 PHASES; THIS PHASE I PROPOSAL COVERS THE INITIAL SYSTEM DESIGN AND EVALUATION TO THE PERFORMED USING DATA TAKEN FROM EXISTING ACT DEVICES AND INSERTED INTO A PERFORMANCE MODEL FOR THE OPERATIONAL SYSTEM.
