The problem that damage effectiveness evaluation on the time sensitive group targets for trajectory correction rocket carrying with terminal-sensitive projectiles is discussed in this passage. Firstly, considering the condition that one trajectory correction rocket carrying with terminal sensitive projectiles striking single target, we introduced its damage probability model. Secondly, on the basis of the above research, the model with point to point is expounded to the model with group to group. Thirdly, based on the condition that close monitored targets and emergent targets, we introduce the probability of targets being present, and the damage effectiveness evaluation is further introduced based on the probability. Finally, the numerical simulation shows the effectiveness of the method, and the residence time of time sensitive targets correlated with damage effectiveness evaluation are further analyzed.
