Physics Based Discrimination Algorithms with New OPTISIG

East West Enterprises Inc. (EWE) proposes to develop physics based discrimination algorithms to improve GMD's ability to identify target objects in cluttered environments. Robust discrimination ability can be facilitated with a high-speed, high fidelity,signature code that can rapidly simulate all of the assumed threat objects, as seen from multiple sensor locations. This high-speed code would rapidly generate the assumed threat picture as seen by each of those sensors, and the results would be comparedwith the actual threat being viewed. If they don't match, new threat simulations are quickly generated and compared with the threat in an iterative scheme, until a good match is achieved. This approach requires (1) a high-speed, high fidelity, signaturecode and (2) an intelligent discrimination algorithm set, to rapidly converge the simulated threat to a good match with the actual threat. EWE proposes to use a new, enhanced version of OPTISIG, (called TSI-OPTISIG), as the high-speed, high fidelity,signature code, and we propose to develop an intelligent discrimination algorithm set (based on the physics models within that signature code) that will rapidly match the simulated threat to the actual threat. The technology proposed here and the algorithms to be developed will be of great benefit to the Project Hercules, THAAD, GMD and other military programs
