Research On The Assignment And Cooperative Defense Of Multi-missile

Ballistic missiles play an important role in modern warfare.Moreover,with the progress of technology,the capability of ballistic missile has been greatly improved,such as:the effective range?lethality and strike accuracy.As more and more countries have ballistic missiles,the corresponding anti missile defense system is highly valued by military powers.Multi missiles coordinated defense is an important means to intercept ballistic missiles and is an indispensable part of the anti missile defense system.In this paper,the flight characteristics of the reentry ballistic missile are analyzed,and the multi missile defense task planning technique is studied.The ballistic missile has long range,high reentry speed and short reentry flight time.In order to improve the interception probability,firstly genetic algorithm is applied to optimize the parameters of the incoming ballistic missiles,real-time prediction of flight trajectory and falling point is made according to model of free flight and reentry.The simulation results show that this method can effectively predict the ballistic missile reentry trajectory.Secondly,according to the incoming target information obtained,the compound guidance law of middle distance interceptor is designed.This guidance law compounds the initial program guidance,the optimal midcourse guidance of predictive intercept point and the terminal guidance with impact angle constraints.The handover conditions of each guidance stage are given,and the effectiveness of this guidance law is verified by simulation.Then,attack zone is calculated.To overcome the shortcoming of long operation time of traditional calculation method,the online algorithm of dynamic attack zone for Missile after being launched proposed.Through simulation analysis of the traditional intercept area and dynamic interception area,the feasibility of this algorithm is verified.Finally,based on the mathematical model for multiple incoming targets,the task allocation is carried out by dynamic weight particle swarm optimization(PSO).In order to realize the purpose of saturated interception for multiple incoming ballistic missiles,single layer multi bomb coordinated interception and multi-layer cooperative interception is designed.The simulation of target assignment,multi interceptor cooperation for the same target and multi-layer interception is carried out,and its results show that this scheme can intercept the ballistic missile accurately.
