强光对微光装备作用效应仿真研究

Simulation research on influence of strong light on low light level equipment

通过研究火焰的辐照特性、目标辐射与反射特性、传输路径大气效应,建立了野外强光干扰试验的光学辐射和传输模型;通过研究微光装备的信号响应特性模型、光学传递函数模型、渐晕和噪声模型,建立了强光作用下的增益特性、饱和特性和对比度特性模型,揭示了干扰光强与装备响应的变化规律;并在此基础上,构建了强光干扰动态场景与仿真平台,实现了强光源干扰微光系统综合效应模拟。

The optical radiation and transmission models of strong-light jamming experiment in field were established through the research of blaze radiation characteristics,target radiation,target reflection,and atmosphere transmission.The models of gain characteristics,saturation characteristics and contrast characteristics under high light were established through the research of signal response characteristics model,OTF model,vignette and noise model,and the relationship between jamming light strength and equipment response were obtained.Based on this,dynamic scene and simulation platform of high light jamming were established,and the combined effect of high light jamming on photoelectric equipment was simulated.
