摘　　要：为了准确测试破片群的飞行方向和位置,研究了六幕光幕靶测量破片群飞行参数测试算法.依据位置标识器上的破片位置坐标和破片穿过六个光幕的时刻序列,提出了一种识别各破片实际飞行速度和位置的算法.根据实际破片飞行的约束条件和位置标识器上留下的破片穿孔位置坐标,计算出穿过光幕靶的每一枚破片的飞行参数.在计算机上对所提算法进行了仿真,结果表明研究的算法能够有效地剔除虚假时间组合序列,可准确计算出完整穿过六光幕阵列中每一枚破片的飞行速度.In order to measure the fly direction and measure flying parameter of swarm of fragments with distinguishes the sequence from a group of sequences impacting position of fragments, an algorithm to six light screens is researched. The algorithm that of time is put forward according to the coordinates of fragment position on a location identifier and all the sequences of the fragments. The sequences of time are arranged with every permutation which is supposed to be a real fragment time sequence. A real time sequence can be distinguished and recognized from all permutations by comparison with the coordinates calculated with permutation, the real position on the location identifier and the restriction on the flying direction and passing times. The algorithm is proved accurate and effective by the simulation.
