ADVANCED MODULATION DOMAIN EMITTER SORTING CHARACTERIZATION AND IDENTIFICATION TECHNIQUES

POTENTIAL SORTING TECHNIQUES FOR USE BY RADAR WARNING RECEIVERS (RWR) AND DECEPTION ELECTRONIC WARFARE (DECM) SYSTEMS ARE IDENTIFIED FOR HANDLING ADVANCED EMITTERS DISPLAYING COMPLEX MODULATION TYPES. THEIR EXPECTED PERFORMANCE IS ANALYZED IN TERMS OF THEIR CAPABILITY TO MEET PROCESSING SPEED, ACCURACY, AND PARAMETER MEASUREMENT REQUIREMENTS. THE INVESTIGATION ALSO DESCRIBES THE HARDWARE AND SOFTWARE IMPLEMENTATION IMPLICATIONS FOR EACH TECHNIQUE AND INVOLVES GENERATING SPECIFICATIONS FOR THE OPTIMUM TECHNIQUES, DEMONSTRATING THE PERFORMANCE USING A BRASSBOARD, AND PROVING THE FEASIBILITY OF INCORPORATING THESE NEW TECHNIQUES INTO PRESENT RWRS AND DECM SUITES. THE TECHNIQUES DEVELOPED ARE CAPABLE OF PROVIDING FAST, ACCURATE, AND HIGH RESOLUTION OF INTRAPULSE SIGNAL CHARACTERISTICS SUCH AS FREQUENCY (CHIRP), PHASE (PSK), AND MODULATION LINEARITY, PHASE SHIFT AND CORRESPONDING PSK CODE LENGTH/BIT LENGTH, ETC. FOR USE IN SIGNAL SORTING AND CATALOGING. THE TECHNIQUES DEVELOPED ALSO ALLOW FOR AND WOULD SUPPORT 1). ALLOWING EMITTERS AND/OR PLATFORM FINGERPRINTING OF COMPLEX MODULATED SIGNALS BASED ON THE DISTINCTIVE CHARACTERISTICS MEASURED USING NEW SORTING TECHNIQUES AND 2). SUPPORTING THE REGENERATION OF THE RECEIVED SIGNALS AT A LATER TIME FOR DECEPTION JAMMING. ?????????
