According to the motion analysis of the BAT sub-ammunition and its hit accuracy requirements, the installation of micro-pulse engineer for terminal trajectory correction was proposed. Its entire control system components and function were introduced. The control system was divided into detection module, main control module and ignition drive circuit module, and the ignition drive circuit was designed. By analyzing the security needs, the insurance circuit was pulsed to make the old hardware circuit improved and optimized based on the security ideas. The results showed that the control circuit had a good performance and certain application value.%根据对BAT子弹药的运动分析以及命中精度要求，提出一种加装微型脉冲发动机进行末段修正的思想。介绍了BAT子弹药在加装末段脉冲修正机构之后整个控制系统组成及其功能，将整个控制系统简化为探测模块、主控制器模块和点火驱动电路模块，主要对点火驱动模块硬件电路进行了设计，并结合安全性需求这一思想加入了保险电路，对其点火驱动电路进行了改进与优化。分析结果表明：该控制电路具有良好的性能，有一定的应用价值。
