摘　　要：后效冲量误差是引起弹道导弹飞行弹道误差和命中误差的一个重要误差源。根据冲量原理和小偏差理论给出了后效冲量误差引起导弹命中误差的一种计算方法和模型,提出了一种用关机分离方程控制射程的方法。仿真计算表明,该方法可彻底消除后效冲量误差,进而消除后效冲量误差产生的命中误差。After-working impulse is main source to ballistic missile flight trajectory error and hit error. On the basis of impulse fundamentals and short offset theory, a calculation method and its model of missile hit error generated by after-working impulse are given. Then, a method that the missile range is controlled by the rocket shutdown disbranch equation is presented. This method can get rid of after-working error and missile hit error.

关 键 词：后效冲量 命中误差 误差控制
