Guidance Law for Attacking Active Defense Aircraft

In the active defense scenario, the aircraft launches a defender to protect itself. In this paper, the feasible region for the attacking missile (attacker) pursuing the aircraft (target), and the infeasible region for the attacking missile evading the defender, are investigated by using the traditional one-to-one optimal guidance law. If the attacker uses the one-to-one guidance law, it is difficult to hit the aircraft. The attacking guidance law is presented for the attacker to win the game. The guidance law is divided into three phases. In phase one, the attacker pursues the aircraft until the zero-effort-miss distance between the attacker and the defender reaches the boundary. In phase two, the attacker evades the defender until the engagement between the attacker and the defender comes to an end. In phase three, the attacker pursues the aircraft by using optimal pursuit guidance law. The three phases guidance law is verified by nonlinear simulation.
