Abstract:

WITH THE PROLIFERATION OF RADARS THAT USE RAPIDLY VARYING TRANSMITTED PULSE PARAMETERS TO AVOID DETECTION AND RECOGNITION, UNINTENTIONAL MODULATION ON SAID PULSES MAY BECOME A PRIMARY RECEIVED SIGNAL SORT PARAMETER, E.G. A MENS OF ASSOCIATING THE INTERCEPTED PULSE TRAIN WITH A "KNOWN" EMITTER. USE OF UNINTENTIONAL MODULATION ON PULSES (UMOP) AS A SORT PARAMETER CAN PROVIDE BETTER SIGNAL RECOGNITION AND BETTER PARAMETER MEASUREMENTS AND LOCATION COMPUTATIONS THROUGH GENERATION OF MORE VALID ASSOCIATIONS WITH "KNOWN" EMITTER PULSE TRAINS AND, THEREFORE BETTER RECOGNITION OF INTERCEPTED SIGNALS. ACCORDINGLY, A PHASE I STUDY IS PROPOSED TO INVESTIGATE THREE APPROACHES TO THE MEASUREMENT AND CHARACTERIZATION OF UMOP, EACH ENTAILING THE GENERATION OF DIGITIZED DESCRIPTIONS OF INTERCEPTED PULSED SIGNALS FOR COMPARISON AGAINST DIGITAL DESCRIPTORS STORED IN A SIGNAL LIBRARY. THESE THREE APPROACHES INCLUDE: FOURIER FREQUENCY SPECTRAL ANALYSIS, PULSE SHAPE, AND PULSE SHAPE IN COMBINATION WITH FM DETECTOR RESPONSE. SPECIAL EMPHASIS WILL BE APPLIED TO THE PROBLEMS OF UMOP DISTORTION FROM SIMULTANEOUS PULSE RECEPTION AND MULTIPATH RECEPTION. SAMPLING RATES, TIME, FREQUENCY, AND AMPLITUDE QUANTIZATION STEPS NECESSARY FOR THE THREE APPROACHES WILL BE ANALYZED AND RECOMMENDATIONS MADE ON THE BEST COMPROMISE OF RESULTS, COST, COMPLEXITY, AND DESIGN RISK WITH A BLOCK DIAGRAM AND SPECIFICATION FOR THE RECOMMENDED APPROACH TO A UMOP PULSEASSOCIATED POST RECEIVER.
