RETRODIRECTIVE ANTENNA BARRAGE JAMMER

SEA WILL DEVISE A JAMMER CONCEPT THAT WILL JAM THREAT RADARS OVER THEIR ENTIRE OPERATING FREQUENCY. THE CONCEPTUAL JAMMER WILL SURVIVE REENTRY AND OPERATE THROUGHOUT THE ENDO-ATMOSPHERE. THE PRINCIPAL ELEMENT OF THE DESIGN IS A RETRODIRECTIVE LINEAR ARRAY WITH HIGH-GAIN AMPLIFIERS WHICH WILL RECEIVE THE THREAT RADAR SIGNAL, AMPLIFY AND/OR PROCESS IT, AND REDIRECT A JAMMING SIGNAL BACK TO THE THREAT RECEIVER. AMPLIFICATION POWER WILL BE SUPPLIED BY A BATTERY PACK CONTAINED WITHIN THE VEHICLE. THE MAJOR ADVANTAGE OF THE RETRODIRECTIVE ARRAY IS THAT THE ANTENNA MAIN LOBE IS DIRECTED AT THE THREAT RECEIVER, WHICH ENHANCES JAMMING EFFICIENCY. THE FOCUS OF THIS EFFORT WILL BE TO DETERMINE THE ANTENNA PERFORMANCE, BATTERY POWER, SIGNAL PROCESSOR, AND REENTRY VEHICLE DESIGN REQUIREMENTS FOR AN EFFECTIVE JAMMER, BASED UPON THE THREAT RADAR SPECIFICATIONS, THE PERTINENT ENGAGEMENT SCENARIOS, AND THE WEIGHT AND SIZE CONSTRAINTS. THE FINAL REPORT WILL PRESENT THE FEASIBILITY OF THE JAMMER CONCEPT, AREAS OF TECHNICAL RISK, AND A DESCRIPTION OF THE DESIGN.
