摘　　要：建立了母舱推力对落点影响的运动学模型,提出了分导调整时间的计算方法,仿真结果表明,分导顺序首先考虑最远目标点时,推力偏差作用的时间最短,对精度影响最小。对战场决策具有一定的辅助作用。Precision evaluation is very important during the actual war of multiple independent reentry vehicle（MIRV）.According to the different separation sequence of MIRV,the thrust errors of the mother warehouse have different influence on the impact point deviation.Based on the impact point deviation brought by mother warehouse thrust,the kinematics models were set up in the paper.The method of computing the regulative time of the MIRV was got at the same time.The simulation calculations indicate that the acting time of the thrust error is shorter and accuracy is better when the first aim is the farthest.The results have a pivotal action when command department decision-making for battlefield.
