摘要

The cooperative interception trajectories generation of multiple interceptors to hypersonic targets is studied.First,to solve the problem of on-line trajectory generation of the single interceptor,a generation method based on neighborhood opti-mal control is adopted.Then,when intercepting the strong ma-neuvering targets,the single interceptor is insufficient in ma-neuverability,therefore,an on-line multiple trajectories genera-tion algorithm is proposed,which uses the multiple interceptors intercept area(ⅡA)to cover the target's predicted intercept area(PIA)cooperatively.Through optimizing the interceptors'zero control terminal location,the trajectories are generated on-line by using the neighborhood optimal control method,these trajecto-ries could make the ⅡA maximally cover the PIA.The simulation results show that the proposed method can greatly improve the interception probability,which provides a reference for the colla-borative interception of multiple interceptors.
