能识别弹丸飞行方向的弹丸空间炸点三维坐标测试方法

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...

Study on the space burst test system used in proximity fuze projectile

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.
