Abstract

A PASSIVE SINGLE-SITE ESM TARGET RANGING (AND TARGETING) TECHNIQUE SHOULD BE A VALUABLE ENHANCEMENT TO EXISTING ESM OPERATIONAL CAPABILITIES IN THAT IT AVOIDS THE COORDINATION AND MULTI-TARGET/ MULTI-SITE CORRELATION PROBLEMS. THE PHASE I ANALYSIS OF THE GROUNDTO-AIR PROBLEM SHOWED MUCH PROMISE FOR THE TECHNIQUE IF DOPPLER FREQUENCY CAN BE MEASURED WITHIN 1 KHz. SINCE THERE IS CURRENTLY MORE INTEREST IN APPLICATION OF THE TECHNIQUE TO THE AIR-TO-AIR AND AIR-TO-GROUND PROBLEMS (E.G., RPV PLATFORMS), THIS PHASE II PROPOSAL ADDRESSES THE FURTHER DEVELOPMENT OF THE ALGORITHM AND A REALISTIC DEMONSTRATION OF THE TECHNIQUE USING AN AIRBORNE ESM RECEIVER. THE ALGORITHM WOULD BE REFINED USING A MORE REALISTIC SIMULATION, THE REAL-TIME DESIGN WOULD BE IMPLEMENTED ON A MICROCOMPUTER WHICH INTERFACES WITH AN ESM RECEIVER/SIGNAL PROCESSOR AND THE AIRCRAFT NAVIGATION SYSTEM, AND A TEST PLAN WOULD BE DEVELOPED. AFTER COMPLETION OF THE TEST, THE RESULTS WOULD BE ANALYZED AND DOCUMENTED. IN ADDITION, THE FEASIBILITY OF MEASURING DOPPLER FREQUENCY TO THE REQUIRED ACCURACY WILL BE ANALYZED.
