光电干扰机的干扰机理研究

Research of the photo-electric jammer’s jamming principle

文中以初升太阳式调制盘为例，分析了调幅式调制盘红外导引头的干扰原理，导出了当目标投射到导引头上及存在多种干扰时导引头的输出误差信号，并简要讨论了干扰的效果。最后提出了一种实现干扰的方案。

An analysis is given of the jamming principle of an infared seeker with an amplitudede-modulated chopper,in which a rising sun choppcr is used as an example. The seeker’s out-puterror signais are devclopcd when a target is radiating at the seeker and when different jam-mings also exist.A bricf discussion is given of the jamming effect.At last,a scheme is putforward to realize the jammings.
