Abstract: In the missile defense system, there is not only the continuously evolving of trajectories, but also the decision of the event strategy. The differential game and the event game cannot effectively describe the hybrid characteristics alone. Therefore, the missile defense system was regarded as a kind of hybrid system, and hybrid game modeling method of missile interception process (MIP) was proposed. Then the event game model of missile interception was established based on the HSTPN (hybrid stochastic timed Petri net), and the differential game model of the missile interception process was established based on the dynamic model of the missile. Taking the “Minuteman Ⅲ”as the example, the hybrid process was simulated with some practical cases. It was turned out to be that the hybrid interception description scheme based on hybrid games can describe not only the continuous trajectories of missile, but also selection of strategy.

Key words: missile interception, hybrid game, hybrid stochastic timed Petri net, event game, differential game
