去年海湾战争使军队认识到制导、导航和瞄准系统的性能对各种透光整流罩和窗口质量和状态的依赖程度。波斯湾大气中的尘、沙和盐份引起的光学元件快速退化,迫使发展更换和再抛光的定量判据,等到飞行员抱怨时才更换已严重低于标准的系统性能和老化,才去整修光学元件已不经济。如果整流罩或窗口被磨擦划伤或产生凹坑,系统的透过率、分辨率和灵敏度都将下降。另外,表面粗糙度增加引起入射阳光散射,产生的闪耀会干扰“灵巧”传感器。尽管散射是系统
Last year’s Gulf War made the military aware of the dependence of the performance of the guidance, navigation and aiming systems on the quality and state of the various fairings and windows. The rapid degradation of optical components caused by dust, sand and salt in the Persian Gulf atmosphere has forced the development of quantitative criteria for replacement and refinishing until the pilot complains about changing system performance and aging, which are significantly below standard, before refurbishing optics Component is not economical. If the cowl or window is scratched or pitted, the system’s transmittance, resolution, and sensitivity will decrease. In addition, the increased surface roughness causes incident sunlight to scatter and the resulting sparkle can interfere with the “smart” sensor. Although scattering is a system
