摘要/Abstract

摘要： 六光幕阵列天幕立靶是测量速射武器连发弹头着靶坐标的主要设备。针对现有光幕阵列理想模型下测量不确定度分析无法满足其工程实际中测量需求的不足，在理想模型和工程模型下综合考虑双N形六光幕阵列测量不确定度的影响因素，仿真分析了光幕阵列结构参数不确定度、布靶参数不确定度、过幕时刻序列不确定度、光幕垂直度不确定度、靶体水平和平行布放不确定度及弹头速度方向角等各项因素对着靶坐标测量不确定度的影响规律。通过建立的评价函数对各因素的影响作用进行评价。结合工程实际对所有因素影响下的不确定度进行合成，得到选定的1 m× 1 m靶面内不确定度分布。试验表明，实弹测量结果与分析结果具有较好的一致性。

Abstract: Six-light-screen vertical target is an important equipment for the coordinate measurement of rapid-fire weapons. Since the measurement uncertainty analysis based on an ideal model cannot meet the requirement of engineering practice, the coordinate measurement uncertainty of double N-shaped six-light-screen array was considered in the engineering model. All the factors, such as the calibration uncertainty of structure parameters, the measurement uncertainties of target distance and height difference, the time extraction uncertainty, the uncertainty of light-screen verticality, the placement uncertainty of vertical target and the projectile incident angle, etc., are analyzed, respectively. The influence of each factor is evaluated by establishing evaluation function. The synthetic uncertainty is calculated, and the maximum distribution of measurement uncertainty in 1 m×1 m target area is simulated. The results show that the experimental results of live ammunition are in well agreement with the analyzed results. Key
