In the Phase I, IFT collaberates with University Partner to propose a decision support tool called the stochastic adaptive nonlinear differential game tool (SANDGT) for persistent and risk-averse 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 satellite systems and adversarial space objects, which may bring radio jamming and interference to normal space communications, or perform orbit maneuvers for avoiding 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) a Google Earth based multi-view and multi-layer visualization system.
