摘要
针对小尺寸高速飞行目标速度快、散布范围大的特点,在现有光幕测试技术基础上,研究高灵敏度、大面积探测光幕镜头式光幕靶的工作原理,设计了一种可监测镜头式光幕靶噪声且具有程控滤波功能、程控放大功能以及阈值电压可调控的信号处理电路.采用气枪弹进行实弹测试验证.试验结果表明:所设计的信号处理电路在镜头式光幕靶中的应用是可行的.
In view of the characteristics of fast and wide range of small-sized high-speed flight targets,the working principle of high sensitivity and large-area detection of the light curtain is studied,which based on the existing light curtain testing technology.The signal processing were designed.The circuits not only can monitor the noise of the lens type light screen and control the threshold voltage,but also have the function of program-controlled filtering,program-controlled amplification.By testing the circuits with bullets,it shows that the design of the signal processing circuit is feasible used in the lens type light curtain..
