The simulation study of damage assessment of a surface-to-air missile system attacked by an anti-radiation missile and the optimization of fuze-warhead coordination

Abstract

The final damage effectiveness of warhead is the most important objective in missile system design. To obtain the damage probability of a certain anti-radiation missile warhead against a typical field surface-to-air missile system and find the optimal fuze-warhead coordination strategy, the studies of modelling, simulation and optimization are carried out. First, the vulnerability of the target is analysed and the target vulnerability model is established. Secondly, the calculation models of fragments field and over-pressure field are established to realize the calculation of encounter between warhead and target. Finally, the damage assessment model is established to calculate the damage probability of the parts and the whole system. Through Monte Carlo simulation, the single-shot damage probability of the missile is obtained when the parameters of the encounter between warhead and target are randomly selected according to a certain probability distribution. And the optimal fuze control strategies of the missile at different entrance angles are obtained through optimization calculation. If the entrance angle of the missile cannot be identified, the optimal fuze initiation strategy of the anti-radiation missile in this paper is a delay of 13ms. The results show that the research method of this paper can be applied to the missile weapon system with the function of entrance angle identification to maximize the damage efficiency.
