SURFACE ACOUSTIC WAVE CHIRP TRANSFORM CORRELATOR FOR SCORING RECEIVER DEVELOPMENT

THREAT SIMULATORS CAN MAKE BENEFICIAL USE OF SURFACE-ACOUSTIC-WAVE (SAW) DISPERSIVE DELAY LINE (DDL) DEVICE TO SIMULATE ENEMY RADAR CHARACTERISTICS. HOWEVER, A MORE IMPORTANT APPLICATION FOR SAW DDL DEVICE IS IN "SCORING RECEIVER". THE RECEIVER WOULD SERVE TO ANALYZE AND EVALUATE THE ECM GENERATED IN RESPONSE TO THE THREAT. THIS NOT ONLY PERMITS EVALUATION OF ECM EFFECTIVENESS, BUT ALSO BE USED TO TRIGGER A REALISTIC THREAT SYSTEM RESPONSE TO THE ECM. THIS IS AN IMPORTANT PART OF THE TRAINING MISSION. THE QUALITY OF THE SCORING RECEIVER DEPENDS ON THE CHIRP TRANSFORM CORRELATOR. HENCE, PHASE I OBJECTIVE IS TO PERFORM A FEASIBILITY STUDY ON SUCH CORRELATOR USING THE STATE-OF-THE-ART SAW DISPERSIVE FILTERS AND PHASE II EFFORT IS TO IMPLEMENT A HARDWARE FOR DEMONSTRATION.
