Guidance laws for attacking defended target

In this paper, two new guidance laws based on differential game theory are proposed and investigated for the attacker in an attacker-defender-target scenario. The conditions for the attacker winning the game are analyzed when the target and defender using the differential game guidance law based on the linear model. The core ideas underlying the two guidance laws are the attacker evading to a critical safe boundary from the defender, and then maintaining a critical miss distance. The guidance law more appropriate for the attacker to win the game differs according to the initial parameters. Unlike other guidance laws, when using the derived guidance laws there is no need to know the target and the defender's control efforts. The results of numerical simulations show that the attacker can evade the defender and hit the target successfully by using the proposed derived guidance laws.
