  This paper addresses the active target defense differential game where an
Attacker missile pursues a Target aircraft. A Defender missile is fired by the
Target's wingman in order to intercept the Attacker before it reaches the
aircraft. Thus, a team is formed by the Target and the Defender which cooperate
to maximize the distance between the Target aircraft and the point where the
Attacker missile is intercepted by the Defender missile, while the Attacker
tries to minimize said distance. The results shown here extend previous work.
We consider here the case where the Defender is faster than the Attacker. The
solution to this differential game provides optimal heading angles for the
Target and the Defender team to maximize the terminal separation between Target
and Attacker and it also provides the optimal heading angle for the Attacker to
minimize the said distance.
