ACOUSTIC CHARGE TRANSPORT DIGITALLY PROGRAMMABLE TRANSVERSAL FILTER ENHANCEMENT OF ESM/ATD NCTR SENSITIVITY AND SEL....

THE OPERATIONAL PROBLEM ADDRESSED IS LONG RANGE PASSIVE "HOSTILE" TARGET RECOGNITION FOR OWN FIRE CONTROL RADAR SET-ON. THE SPECIFIC PROJECT OBJECTIVE IS TO DEMONSTRATE DIGITAL SET-ON OF AN ELECTRONIC DECISIONS, INC (EDI) ACOUSTIC CHARGE TRANSPORT (ACT) DIGITALLY PROGRAMMABLE TRANSVERSAL FILTER (DPTF), BY A PREVIOUS RADCON DEVELOPED, CLASSIFIED ESM/ECM RECEIVER, FOR ENHANCED SENSITIVITY AND SELECTIVITY OF ANOTHER RADCON DEVELOPED, CLASSIFIED ESM RECEIVER, WHICH EXTRACTS UNIQUE TARGET PLATFORM IDENTIFIERS . THESE RADCON PROCESSORS HAVE BEEN DEVELOPED UNDER PREVIOUS SBIR PHASE II CONTRACTS. THE PROCESSES APPLY GENERIC TRANSFORM AND CORRELATION MATHEMATICS. SIGNIFICANT EXPLOITATION HAS BEEN MADE OF EMERGING ANALOG TECHNOLOGY FOR INFORMATION EXTRACTION AND EMERGING DIGITAL SPEED FOR REAL TIME LOGIC CONTROL. THIS PROGRAM APPLIES THE DEVELOPING ANALOG DPTF AS A NEAR REAL TIME ADAPTIVE PRESELECT FILTER, COVERING THE 10OMHZ INTERMEDIATE FREQUENCY (I.F.) REGION, BANDWIDTH 15OMHZ. THE ESM/ECM RECEIVER, WHICH PROVIDES DPTF SET-ON, INCLUDES A DYNAMIC SORT/TRACK/PREDICTOR OF PRIORITY EMITTER'S NEXT CARRIER FREQUENCY AND PULSE TIME OF ARRIVAL. NECESSARY HARDWARE WILL BE OBTAINED AS GFP. ALL TESTS WILL BE CONDUCTED IN THE RADCON MICROWAVE LABORATORY. ANTICIPATED RESULTS ARE INCREASED SENSITIVITY BY THE ORDER OF 2ODB AND INCREASED SELECTIVITY IN EXCESS OF 5ODB. ANTICIPATED BENEFITS ARE INCREASED TRACK RANGE, THROUGH ANTENNA BACKLOBES, OF LOW PEAK POWER EMITTERS; REDUCED INTERFERENCE IN COMPLEX ENVIRONMENTS, FOR PASSIVE NON COOPERATIVE TARGET RECOGNITION (PNCTR) ENHANCEMENT OF DOD GUIDED MISSILE INTERCEPT SYSTEMS. PROCESSES ARE GENERIC WITH POTENTIAL COMMERCIAL COMMUNICATION SYSTEM APPLICATION.
