摘要
在靶场测试领域,触发器主要用于探测弹丸出射时产生的物理现象,并输出弹丸击发零时刻触发信号,以启动不同的后续弹道测试设备工作,实现多参数的同步。现有触发器易受环境影响,体积较大不易搬运,使用局限性较大。为解决以上局限性,通过研究飞行弹丸在终点弹道段红外辐射特性,选择合适的中波红外探测器,设计中波红外触发器,通过光学结构对中波红外信号聚集,聚焦在PbSe探测器的光敏面上,设计相应的信号处理电路,实现对弹丸的准确探测。经实验验证,该触发器能够在35 m内对弹丸进行有效探测,输出可靠触发信号,探测灵敏度高,具有良好的环境适应性和可靠性。
In the field of shooting range testing,the trigger is mainly used to detect the physical phenomena generated when the projectile is fired,and output the trigger signal at the zero time of the projectile firing to start different subsequent ballistic testing equipment to achieve synchronization of multiple parameters. Existing triggers are easily affected by the environment,and are difficult to handle due to their large size,and have relatively large usage limitations. In order to solve the above limitations,the infrared radiation of the flying projectile in the terminal ballistic section is studied in this paper. A suitable mid-wave infrared detector is selected. A mid-wave infrared trigger is designed. The mid-wave infrared signal is gathered through an optical structure,and is focused on the PbSe detector. Corresponding signal processing circuit is designed on the photosensitive surface to realize accurate detection of projectiles. Tests have verified that the trigger can effectively detect projectiles. It has high detection sensitivity,and has good environmental adaptability and reliability.
