摘要
针对工程中3发及以上弹丸同时过幕为极低概率事件,提出一种基于三角阵列探测的双弹丸识别方法。采用光电探测器件搭建三角形测量阵列,配合3个一字线激光器构成双弹丸同时着靶识别系统。建立其测量模型,分析了x、y方向上的理论误差变化规律。静态模拟试验表明:有效探测区域为1 m×1 m,弹丸口径为5.8 mm的条件下,x、y方向上的实际测量误差分别为±3.5 mm与±3.2 mm,可有效地识别间距不小于4.74 mm的同时着靶双弹丸。
In engineering,the probability,which three or above projectiles simultaneously passing through the detection screen,is extremely low.Accordingly,a double projectile recognition method based on triangular array detection was proposed.Firstly,a triangular detection array was constructed using photo-detector,and a dual-projectile simultaneous target recognition system was constructed by combining three monosyllabic lasers.Then,the measurement model was established,and the change rule of theoretical error in X and Y directions was analyzed.Static simulation tests show that under the condition of effective detection area of 1 m×1 m and projectile caliber of 5.8 mm,the actual measurement errors in the X and Y directions are±3.5 mm and±3.2 mm,respectively.The method can effectively identify double projectiles with spacing of not less than 4.74 mm.
