摘要
激光箔条云对激光有很高的散射率,光电对抗中越来越多地采用激光箔条云作为激光无源假目标实施无源干扰,或作为激光漫反射体与激光有源干扰设备配合使用,实施激光角度欺骗干扰。基于箔条云对激光的散射原理,分析了两种干扰方式的原理,设计了激光箔条云对激光导引头的有源角度欺骗干扰实验方法,给出了所需测试设备及布站要求。结果表明,干扰效果理想。该干扰方法具有灵活、机动、快速等特点,可作为一种激光有源角度欺骗干扰的新手段。
The clouds of laser chaff have high scattering ratio over laser. In electro-optical countermeasure, to implement passive jamming, the clouds of laser chaff have been used as false target of laser more and more. Possibly, to actualize laser angle deception jamming, they can be used as diffuse reflection object, cooperating with laser active jamming equipment. Based on the scattering theory of clouds of laser chaff over laser, the jamming theories of the two interference mode are ana- lyzed. And the experiment method is designed, that the clouds of laser chaff interfere the laser seeker by angle deception. Besides, the needed testing equipments and layout demand are given. Finally, the results show that the effects are ideal. The method is agility, mobile and quick and can be used as a new measure of laser active angle deception jamming.
