Coordinated guidance strategy for heterogeneous missiles intercepting hypersonic weapon

To solve the defense problem of hypersonic weapon, a coordinated guidance strategy based on modified proportional navigation guidance law and consensus algorithms for heterogeneous interceptor missiles is proposed. The heterogeneous missiles are classified into leader missile and follower missiles. The leader missile is equipped with high-performance seeker, intercepting the target under modified proportional navigation guidance law. The low-cost follower missiles track the leader missile by consensus algorithms. A consensus tracking protocol which can be used to guide the heterogeneous missiles hitting the target simultaneously is investigated. The Necessary and sufficient conditions for heterogeneous missiles to intercept the hypersonic weapon are presented. Finally the effectiveness of the coordinated guidance strategy is demonstrated by numerical simulations.
