Predictive Regret-Matching for Cooperating Interceptors to Defeat an Advanced Threat

A strategy for using cooperating missiles for missile defence

“…Su et al [2018] consider defending missiles with inferior maneuverability, but do not consider limitations of information from a ground-based radar or inferior performance of on-board seekers. Additionally Rajagopalan et al [2019] apply the Su et al [2018] formulation and find that the cooperative control strategy is not effective against an incoming missile capable of high-acceleration terminal maneuvering. Rajagopalan et al [2019] use a predictive regret-matching algorithm to guide a team of defending missiles to totally cover the incoming missile's reachability.…”

Rajagopalan et al [2019] use a predictive regret-matching algorithm to guide a team of defending missiles to totally cover the incoming missile's reachability. Rather than dividing the acceleration limits of the incoming missiles into a number of regions for the defenders to cover, they first project future positions of the incoming missile based on its speed and acceleration limits, then coordinate the defenders to cover off the incoming missile's reachability.…”

“…A clear difference between this approach and that of Su et al [2018] is that Su et al [2018] does not transition the defending missiles to a different guidance law to intercept the incoming missile. Rajagopalan et al [2019] assume that the defending missiles can see the incoming missile for the entire duration of their flight-they do not model a separate seeking phase where the defenders rely on a ground-based radar to provide updates of the incoming missile's position and velocity.…”
