摘要
针对现有测量装置在测量近炸引信弹丸空间炸点三维坐标时存在的不足, 提出了一种采用6光幕阵列配合火焰探测器测量弹丸空间炸点的三维坐标测试方法。提出的方法包含两台多光幕天幕靶、一台空间炸点火焰探测器和一台多路数据采集仪。两台多光幕天幕靶的6套光路和光电转换部件在空间构成6光幕探测阵列, 当弹丸穿过6个探测光幕时, 多路数据采集仪采集多光幕天幕靶输出的弹丸模拟信号, 经处理得到弹丸穿越某一预定靶面时的弹道俯仰角θ、弹道方位角γ、弹丸飞行速度V以及弹丸着靶坐标(X, Y), 再通过火焰探测器探测弹丸的爆炸时刻T, 利用测得的6个参数进一步计算出弹丸空间炸点三维坐标(X′,Y′,Z′)。经实验证明该方法可行有效, 能够很好地满足靶场近炸引信弹丸空间炸点三维坐标测量的需求。
Abstract
Aiming at the problems of existing device in measuring the projectile proximity fuze three-dimensional coordinate of space burst, a system based on six light-screens principle and flame detector is presented. The system’s main detector includes two sky screens , one flame detector and one multi-channel data logger. The six light-screens detector array is composed by six optical and photovoltaic conversion parts of the two sky screens. When the projectile passes through the six light-screens, the multi-channel data logger records the data of the analog signal produced by the sky screens. The projectile velocity V, angle of incidence θ and γ, target coordinates X and Y can be got by processing the signal. The projectile’s explosion time T can be detected by the flame detector. And then projectile’s three-dimensional coordinate of space burst can be calculated by above-mentioned parameter. The experiment result shows that the system is stable and reliable, and can meet the demand of the shooting range well.
