Research On Cooperation Guidance Method For Interception Of Multiple Targets By Multiple Antiaircraft Missile

With the rapid development of near spacecraft and the significant improvement of the mission requirements of missile interception,the penetration-defense combat of multi-aircraft to multi-missile has become the major ways to win in system confrontation.On the basis of considering the coordination factors among the missiles,this paper designs the most advantageous countermeasure strategy and scheme,aiming at different air attack targets,several kinds of research on cooperation guidance interception and simulation are carried out as fellow:Firstly,aiming at the reentry process of ballistic missile,a series composite guidance law is designed,which uses program initial guidance law,optimal proportional middle guidance law,and sliding mode variable structure terminal guidance law;aiming at the maneuverable NSV,the composite guidance law of midcourse guidance and all-direction attack PID terminal guidance is designed.The simulation results show that two composite guidance methods can intercept the reentry warhead and NSV effectively.Secondly,this part mainly has a research of missile on dynamic attackable zone after launch,considering the shortcoming of low precision and long iteration time of traditional attackable zone.a fast and high precision fitting algorithm is proposed,the feasibility of the algorithm is verified by simulation results.Thirdly,the design method of multi-missile to multi-target cooperative interception strategy is given,and the interception strategy of “target recognition-threat assessment-multi target allocationeffectiveness evaluation” is adopted,the simulation validation the feasibility of the multi-missile cooperative interception strategy,which can effectively protect resources and assign weapon to high-threat targets.Lastly,in order to meet the requirement of multi-missile to multi-targets cooperative attack,the interception scheme and cooperative guidance law of multi-missile to multi-targets are designed with ballistic missile and NSV as interception targets,a multi-layer interception and penetration direction cooperative interception scheme are established,and the corresponding time cooperative guidance law is designed,the simulation results show that the scheme can achieve high-precision interception of multiple targets.
