Abstract

TRACKING WITH A DECENTRALIZED SQUARE ROOT INFORMATION FILTER (SRIF) REPRESENTS A TECHNICAL BREAKTHROUGH THAT HOLDS THE POTENTIAL OF DRAMATICALLY RELAXING BALLISTIC MISSILE DEFENSE (BMD) SENSOR AND COMPUTER HARDWARE REQUIREMENTS. SINCE THE DECENTRALIZED SRIF DISTRIBUTES THE TRACKING CALCULATIONS TO LOCAL AND GLOBAL PROCESSORS WITH AN OPTIMAL STRUCTURE, SENSORS DO NOT HAVE TO BE OVERDESIGNED TO MAKE UP FOR THE INADEQUACIES OF APPROXIMATE SCHEMES THAT DISTRIBUTE TRACKING. THE FEASIBILITY WAS ESTABLISHED IN THE PREVIOUS RESEARCH PHASE OF DECENTRALIZED TRACKING USING A DECENTRALIZED SRIF. A MULTIRATE DECENTRALIZED SRIF WAS DEVELOPED. A NUMERICAL SIMULATION WAS PERFORMED TO COMPARE THE MULTI-RATE DECENTRALIZED CONVARIANCE FILTER TRACKER WITH THE SRIF TRACKER. A HIGH FIDELITY MODEL FOR SELECTED BMD CONFIGURATIONS AND OPERATIONAL CONDITIONS IS BEING DEVELOPED TO FOCUS FURTHER THEORETICAL DEVELOPMENT. A NUMERICAL STUDY QUANTITATIVELY DEMONSTRATING PERFORMANCE IS BEING PERFORMED AND AN ALGORITHM FOR PARALLEL PROCESSING IS BEING DEVELOPED.
