激光引信与预制破片战斗部引战配合设计

针对预制破片弹破片飞散的特点, 提出了一种基于激光近炸引信控制的预制破片战斗部引战配合的设计思路。通过公式推导、Matlab软件仿真和计算预制破片战斗部对等效面积靶板的毁伤, 获得战斗部理想的起爆高度。在理想起爆高度条件下, 选择合适的激光探测视场进行引信设计, 从而完成预制破片弹引战配合在特定条件下的最优设计。结果表明: 在导弹散布误差为5 m、俯仰角为60°, 攻击目标特征为5 m×3 m×3 m的指挥车时, 战斗部起爆高度在4～6 m间, 命中目标的有效破片密度最大, 在此起爆高度内对引信的探测概率和探测高度进行分析、计算得出: 激光引信最优光束发射角在17°～30°。这种引战配合设计对于激光引信控制的预制破片弹的工程应用具有实际的参考价值。

Abstract

Aiming at the fragmentation dispersion characteristic of prefabricated fragment ammunition, fuze-warhead coordination was designed based on prefabricated fragment ammunition controlled by laser proximity fuze. Ideal warhead explosion height was obtained through formula deduction, Matlab software simulation and calculation of target damage at a equivalent area. Under this condition of the ideal explosion height, the laser fuze was designed through selecting appropriate laser beam detection field. Thus a optimal design of fuze-warhead coordination under specified conditions was completed. Results showed that: in the the range of 5 m of the missile dispersion, 60° pitch angle and 5 m × 3 m×3 m command vehicle target, effective fragment density is the biggest at the warhead explosion 4-6 m height. Detection probability and height of the laser proximity fuze are analyzed and calculated at the height interval of the detonating height, the optimal beam emission angle of laser fuze is from 17° to 30°. This design is of practical reference value for the application of the prefabricated fragment ammunition controlled by laser fuze.
