Partial Information Defense Game with an Active Target

This paper studies the partial information defense game with an active target. This type of game considers the influence of both sensing limitation and the moving target, which are common in the real-world conditions. Compared with the stationary target scenario, the defender has more flexibility to capture the intruder when the target is active. Inspired by previous works, we separate the game into four phases and obtain optimal strategies for all agents in each phase, respectively. The lower bound of defender’s winning probability is obtained under some mild assumptions, which is higher than that in the stationary target scenario. An illustrative example is presented to demonstrate the efficacy of the theoretical results.
