Research On Target Damage Evaluation Strategy For The Missile-Target Intersection

The damage effect of the missile and target intersection in the air defense and antimissile environment is an important indicator to measure the performance of the fuze and ammunition.The intersection attitude of the projectile and target is uncertain,and the warhead fragment space formed by the fuze explosion is highly random,which makes it difficult to evaluate the damage effect of the target.How to use the dispersion characteristics of missile-target intersection fragment field to establish different state states of intersection confrontation,and establish the target damage assessment strategy model of fragment space dispersion conditions is crucial.The evaluation strategy model is the key to improve and perfect the target damage evaluation system of air defense and anti-missile system.This paper mainly studies the damage assessment model of game strategy under the condition of missile-target space intersection confrontation.Firstly,based on the space-time confrontation mechanism of missile target intersection,the space analytical model of confrontation attitude is established,and combined with the intersection and confrontation characteristics of missile damage state,the intersection and confrontation correlation model of damage state is constructed.Then,according to the spatial distribution characteristics of warhead fragments,the target intersection anti-damage model of different fragment fields is proposed,the state correlation mechanism of rendezvous countermeasure is studied and the damage model of missile-target rendezvous countermeasure is established,according to the condition parameters of the intersection confrontation state and the damage parameters of the fragments to the target,the target damage rules of different intersection confrontation states and fragment space distribution conditions are clearly established.The damage level is quantified by using the target vulnerability equivalent model,and the target cabin vulnerability tree model is constructed.Combining the characteristics of the interaction between the missile and the target damage confrontation and the game strategy,the target confrontation damage game model is established,and the game strategy set of confrontation damage and the game revenue function of confrontation damage are given.Finally,according to the mechanism of the mixed strategy of the missile-target damage game,the Nash equilibrium solution algorithm based on the missile-target damage game is proposed,combined with the effectiveness evaluation of the intersection confrontation of the Nash equilibrium solution of the single-damage mixed strategy game,the single-damage mixed strategy is extended,and the mixed strategy situation of the multi-damage game is constructed,to deal with the uncertainty of damage revenue of target confrontation game in different fragment fields,the damage assessment system based on game strategy is established.The Nash equilibrium optimal damage strategy situation of multi-damage game model is verified by simulation.The Creator model of static visual missile-target and rendezvous environment is called in Visual Studio 2005 environment.Combined with the model database configured by Vega Prime,the visual simulation platform of missile-target rendezvous and confrontation is built,and the dynamic visual simulation of missile-target rendezvous and confrontation in the game optimal strategy environment is carried out.The simulation results show that the multi-damage evaluation method based on game Nash equilibrium strategy is effective and accurate,which can provide effective theoretical support for target damage evaluation system.
