Unified Interceptor Assignment Algorithms

Detecting, localizing, and intercepting one or more missiles during ascent phase presents a daunting theoretical and practical challenge. Scientific Systems Company, Inc. of Woburn, MA, and its subcontractor, Lockheed Martin, propose a foundational, control-theoretic approach to such problems. It is based on the idea of mathematically modeling a multiplatform-multisensor-multitarget system as SINGLE, JOINTLY EVOLVING STOCHASTIC PROCESS. All relevant information regarding behaviors of all sensors, all platforms, and all targets are inherently integrated into the algorithm design at the outset. As a consequence, all major functionsdata fusion, detection, tracking, navigation, and control, etc., are inherently integrated into a single, unified system. Phase I showed the feasibility assessment by simulating rocket trajectories that account for precise targeting and the specific rocket characteristics of medium range rockets, accurate modeling for the I-2 interceptor, and derived multi-firing solution for neutralizing adversary rockets. The results indicated successful intercept and neutralization by detection and tracking using space based IR sensors for the first 50 seconds (with an accuracy of 300 meters) followed by aided tracking utilizing radars on board a destroyer such as AEGIS (with a resulting combined accuracy of 200 meters), and finally the KV IR sensor is utilized for a resulting total accuracy of 20 meters. Phase II work will emphasize development of more mature prototype interceptor-versus-missile algorithms, to be tested using more realistic environments and data, and at more realistic processing speeds. This will include development of a dual-use commercialization plan with special emphasis on developing working relationships with BMD contractors.
