Protective Mission against a Highly Maneuverable Rogue Drone Using Defense Margin Strategy
The current paper studies a protective mission to defend a domain called the safe zone from a rogue drone invasion. We consider a one attacker and one defender drone scenario where only a noisy observation of the attacker at every time step is accessible to the defender. Directly applying strategies used in existing problems such as pursuit-evasion games are shown to be insufficient for our mission. We introduce a new concept of defense margin to complement an existing strategy and construct a control strategy that successfully solves our problem. We provide analytical proofs to point out the limitations of the existing strategy and how our defense margin strategy can be used to enhance performance. Simulation results show that our suggested strategy outperforms that of the existing strategy at least by 36.0 percentage points in terms of mission success.
