摘　　要：针对天幕靶在炮口测量时,受炮口火光干扰影响的问题,在新研制的以阵列光电探测器为探测核心的天幕靶中,利用炮口火光同时作用在整个阵列光电器件上的特性,在满足天幕靶的探测视场下,将阵列光电器件分成三个探测区,通过分析三个区的火光与弹丸成像信息关系,设计合理的探测电路,将火光干扰降到最低,提高穿越光幕的弹丸成像质量,达到抗火光干扰能力。经靶场实弹射击实验,改进的天幕靶测速精度高达3‰。The sky-screen will be affectted by some factors when it works before the gunpoint, such as firelight, vibration, and so on. The new sky-screen which applies array optic- electric detector as the detecting core can improve the performance of photo-electricity. The feature that the gunpoint light works at the same time in the whole array optoelectronic devices is used to analyze and design the sky-screen, under the condition of meeting the detection visual field request. The relation between gunpoint light and the projectile imaging information are analyzed, and the array optic-electric detector is divided into three parts, and the reasonable detection circuits are designed. These measures minimize the effect of gunpoint light, increase the projectile image quality obviously and eliminate the interference of gunpoint light when the projectile going through the screen. The results of experiment show that the precision of projectile velocity can be up to 3‰ in the improved sky-screen.
