摘要
利用激光束在大气中的传播理论,针对激光束在大气中传播时的辐照度进行分析,提出了一种有意义的告警手段—探测微弱激光辐射进行激光提前告警。介绍了激光告警的发展现状及其本身的特点,阐述了激光告警的截获原理,详细分析了激光提前告警的原理与意义。理论证明通过适当的控制告警接收机对激光辐照度的告警域值,在激光测距机发射激光的扫描阶段,激光直射光束距离告警接收机很远时就可告警,实现提前告警完全可能。
Theory of laser beam propagation in the atmosphere is introduced. The irradiance is analyzed for laser beam propagation in the atmosphere. An early warning approach is put forward for weak laser radiation detection. Status and characteristics of laser warning is introduced. Interception principle for laser warning is described and its significance is analyzed in detail. Theoretically, proper control of laser warning receiver irradiance alarm threshold during scanning phase of a laser rangefinder can provide early warning when the laser direct beam is far away from the warning receiver. And early warning for laser is possible.
