智能地雷探测系统发现目标后,由母雷发射攻顶子弹,子弹通过敏感器识别目标并发射爆炸成形弹丸攻击目标。攻击过程时间短且动作复杂,因此有必要分析命中精度。通过研究运动学原理,建立以攻顶子弹、爆炸成形弹丸、攻击目标相对位置为依据的计算模型,计算了爆炸成形弹丸着点的偏差。计算表明:爆炸成形弹丸的命中精度与攻顶子弹的飞行状态、敏感器的性能和目标运动状态有关。研究结果为智能地雷总体设计提供了理论依据。

After the target is detected by the detection system of intelligent mine, the top-attack submunition is launched by main mine. After the target is identified by sensor, the top-attack submunition emits explosively formed projection (EFP) to attack the target. Due to the attacking process is finished rapidly and complicatedly, the analysis on the impact accuracy of EFP becomes very important. According to the study on kinematics principle, the calculation model based on relative position of top-attack submunition, EFP and target was formed. The results of calculation shows that flight state of top-attack submunition, performance of sensor and motion state of target can influence the impact accuracy of EFP. The study results lay the theoretical foundation for overall design of intelligent mine.
