Abstract: A terminal damage simulation model in target coordinates of multi-purpose missile warhead, including kinematics model, hitting target model, and killing target model of killing element was put forward. Using the kinetics theory, the movement of kill element and target in the ground coordinates can be transformed into the relative movement of killing element in the target coordinates. Therefore, whether the target moves or not, the target vulnerability data can be directly used for killing calcula?tion. It provides a precise simulation model of killing some kinds of movable targets, such as helicopter for multi-purpose guided missile, and a powerful analysis tool for demonstration and design of new multi-purpose guided missile.
