光电探测器的弱点及其新原理的设计

THE DISADVANTAGE OF P.C.C AND ITS NEW PRINCIPLE DESIGN

在轻武器外弹道综合试验中,区截装置所用的光电探测器均是采用“弹尖触发”的原理。本文针对“弹尖触发”所存在的不足,详细介绍了“弹底触发”方案设计的全过程、测试误差分析,以及在“天幕精度靶”中所使用的结果,也进一步证实了在小口径武器试验中,“弹底触发”比“弹尖触发”更具有优越性,而新颖的抗干扰技术则使仪器更添实用性。

The working principle of P.C.C used as measurement equipment is based on 'bullet-point trig during the weapon exterrior ballistic test . In order to decrease the measurement error concerned with problems existed in the bullet-point trig, this paper introduces theprinciple of bullet-bottom trig and neasurement error analysis and the result in application to Sky Screen Precisio n Target.It makes out that the bullet-bottom trig is more significient . and useful than the 'bullet-point trig.
