| 摘 要： | 提出一种抗光干扰光幕靶的设计方法。当光幕靶工作于近炮口距离时,炮口火光会影响光幕靶产生误触发信号,从而影响测试系统的准确度。设计利用了光电器件阵列对火光同时反映的特点,设计光电补偿部件及前置放大减法器,将火光引起的变化的光电流信号抵消掉。分析了设计原理,并用实弹射击的方法验证了电路设计的正确性。

| Abstract: | The gunpoint light will bring an error signal when the optical screen work before gunpoint.It may affects the precision of the system.A design which can avoid the affection of useless light signal was given.The preamplifier-subtracter and expiation parts was used to counteract the variational photocurrent because the photoelectricity element array respond the light signal.The principle of the design was described in detail,and it's exactness was proved through the fireing. |
