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‰。
Aiming at the problem that the canopy target is affected by the muzzle fire when measuring the muzzle, aiming at the characteristics of the array optoelectronic device using the muzzle flare in the newly developed canopy target with the array photodetector as the detecting core, The array photoelectric device is divided into three detection zones under the detection field of vision that meets the sky curtain target. By analyzing the information of the flare and projectile imaging information of the three zones, a reasonable detection circuit is designed to minimize the interference of the flare and improve the light transmission across the light curtain The projectile imaging quality, to anti-fire interference ability. After the shooting range live shooting experiment, the improved speed measurement accuracy of the sky screen reaches 3 ‰.
