一种烟幕对激光遮蔽效果的测量方法研究

摘要:针对野外动态测量烟幕对激光遮蔽效果常采用单路激光的现状,提出了采用两路激光测量烟幕遮蔽效果的方法,解决了利用两路激光测量烟幕遮蔽效果时混合激光信号分选识别、测量方案设计和相关设备的布局等技术难题,实现了对烟幕激光透过率的两路动态实时测量。结果表明:采用两路激光测量烟幕的遮蔽效果,增加了激光透过率数据的采集样本,降低了单路激光烟幕透过率测量的随机性,有效提高烟幕的利用率和测量结果的客观性。

A measurement method of obscuring effect of smoke screen to laser

Aiming at the technology status that the single channel laser is usually used to measure the dynamic shading effect of smock screen in the field,a novel measurement method is proposed for smoke screen shading effect by using two-beam laser,the combined technical problems such as mixed laser signals sorting and code identification,designed measurement scheme and equipment layout are also solved based on the two-beam laser measurement system,the real-time and dynamic smoke screen transmissivity is obtained by utilizing two-channel laser measuring technique.The testing results shows that the novel measuring method is succeeding in increasing the sample size about smoke screen position and laser pathway,the high-randomness shortcoming of the widely used single-channel measurement of smokescreen transmissivity is decreased,and the degree of confidence on the measuring results and smoke screen utilization are also increased effectively.
