分析了鱼眼激光告警系统的工作原理,建立了基于散射探测的鱼眼激光告警系统的探测模型,推导出系统的目标光斑成像公式及目标光斑到达探测系统的单像元能量公式,最后引用美国休斯飞机公司AN/TVQ-2激光目标指示器参数进行数值模拟分析,得出激光传输距离及鱼眼告警系统设置高度与探测器单像元能量的关系。
The working principle of the fish eye laser warning system is analyzed. The detection model of the fish eye laser warning system based on the scattering detection is established. The imaging formula of the target spot and the single-pixel energy formula of the target spot reaching the detection system are deduced. Finally, Hughes Aircraft Company AN / TVQ-2 laser target indicator parameters of the numerical simulation analysis obtained laser transmission distance and the fisheye alarm system set height and detector single pixel energy relationship.
