视觉隐身技术是通过光学方法减小飞机的视觉特征。本文首先介绍了国外飞机视觉隐身技术的发展历史。为了对比实验效果,引进了一个新的技术名词——蓝天背景下目标仰视可视截面积,重点介绍了国外利用电致发光视觉隐身技术在某型无人机上的应用成果,该技术可使无人机飞行高度为100m时,在蓝天背景下的目标仰视可视截面积从0.42m^2下降到1.8cm^2,使无人机实现视觉隐身。最后,展望_r电致发光机翼表面技术在未来新一代战斗机中的应用。

The research purpose of visual stealth regression technology is to lay out a method of achieving a reduced visual signature through the use of optical methods. First, the history of visual stealth regression for aircraft is introduced, then the use of electroluminescent for the visual signal of unmanned air vehicles(UAVs) is summarized. The definition of blue-sky overhead visual cross section(BSOVCS) is brought forward. It is shown that with proper color and luminosity, the BSOVCS of the aircraft dropped from more than 0.42 m^2 to less than 1.8 cm^2 at 100 m. In laypersons terms this indicates that the UAV essentially "disappeared". Finally, applications of electroluminescent wing surface technology in new generation fighter in future are prospected.
