Study on laser warning probability curve in different background sunlight

为了对复杂背景光条件下激光告警设备进行效能评估,基于不同阳光背景开展了激光告警概率曲线的相关研究。首先,对激光告警设备面临的复杂背景光进行了分析;其次,通过理论研究和实验验证,初步获得了激光告警设备在不同强度阳光背景下告警概率曲线变化规律;最后,提出了一种由典型阳光背景下告警概率曲线测试结果推算到不同阳光背景下告警概率曲线的方法。结果表明,阳光背景辐射严重影响着激光告警设备的性能,告警阈值随着阳光辐照强度的增加而增加,告警灵敏度下降。此研究结果有助于进一步提高激光告警设备评估能力。

In order to evaluate the laser warning device in different background light, the study of laser warning probability curve based on different background sunlight was presented. Firstly, the complex light environment for laser warning device was analyzed. Then, preliminary study results of laser warning probability curve variation were obtained by theoretical research and experimental verification. Finally, a calculating method of laser warning probability curve from typical to different intensity irradiance background sunlight was introduced. The results indicate that the background sunlight has a big influence on the performance of the laser warning device, and the warning threshold increases with the increasing of the intensity of sunlight irradiance. The results will be helpful for effect evaluation of laser warning.
