ABSTRACT: Space defense analysis and mission trade studies are vital for the success of space-borne military operation. In this proposal, Intelligent Fusion Technology, Inc (IFT) and its partners propose a decision support tool called stochastic adaptive nonlinear differential game tool (SANDGT) for persistent and risk-advert space situation awareness. The main idea of our approach is to design and numerically solve stochastic adaptive nonlinear differential games, capturing the interactions between friendly satellites systems and adversarial space objects, which may bring radio jamming and interference to normal space communications, or perform orbit maneuvers for collision with in-communication-loop satellites. There are four major components: i) practical game-theoretic modeling with hierarchical structure and three-level dynamics: satellites, sensors, and communication links; ii) versatile information structures with learning algorithms from both pursuer and evader perspectives; iii) numerical and near-optimal solutions to the stochastic adaptive nonlinear games with risk-averse strategies; and iv) Google Earth based multi-view and multi-layer visualization system. This research is built on many IFT"s previous works on dynamic game and application, space communication network, space situation awareness, network security, distributed learning, information fusion, and decision making under uncertainty, etc. BENEFIT: The proposed stochastic adaptive nonlinear differential game tool (SANDGT) for persistent and risk-advert space situation awareness have tremendous applications potential in many military applications. It can be used to protected tactical space communications with dynamic spectrum sharing, routing adaptation and interference mitigations. In addition, some relevant Defense Acquisition Programs within DoD are such as WIN-T Warfighter Information Network-Tactical, JSTARS Joint Surveillance and Target Attack Radar System Aircraft, JTRS GMR Joint Tactical Radio System Ground Mobile Radio, DCGS-N--Distributed Common Ground Station-Navy, DCGS-X (Air Force), DCGS Army (DCGS-A) system. For some of these programs we already have close connections and know considerable program details. The market for military applications is quite large and IFT has successfully transitioned research prototypes for inclusion in DoD contractor research simulations. Other potential commercial applications include civilian network, such as finance, medicine, communications, electric power, nuclear energy, internet service provider, and air traffic control. Anticipated benefits may include significant improvement of end-to-end performance of links with errors and enhancement of TCP over satellite channels. The size of this market is not small and may grow rapidly with the commercial demand in homeland security. We expect the aggregated market size will be similar to that of military applications.
