| 摘 要： | 阐述了脉冲力质心控制的特点和简易制导弹药的弹体追踪制导律原理,分析了探测器最小作用距离对脱靶量的影响。建立了探测器模型和脉冲力控制模型,通过六自由度弹道模型仿真,给出探测器不灵敏域大小对弹丸制导精度的影响。结果表明,减小探测器最小作用距离和优化探测器不灵敏域可以有效提高弹丸的命中精度。Abstract：The characteristic of impulse force control and the principle of body pursuit guidance law of simple guided projectiles were introduced,and the miss distance influenced by the minimum detecting range of photo-detector was analyzed. The models of the photo-detector and impulse force were established,according to the simulation of six degree trajectory model,the hit precision influenced by the non-sensitive area was proposed. The result shows that reducing the minimum detecting range and optimizing the non-sensitive area of photo-detector can improve the hit precision greatly.
