摘　　要：激光近炸引信容易受到各种有源干扰的影响.在对激光的偏振态能够区分目标和背景的原理进行研究的基础上,将激光的偏振特性应用到激光引信中.通过对激光光束的偏振进行调控,达到测距、目标分类、信息保密的目的.引信在工作时,根据目标和背景对激光散射回波信号的偏振取向进行目标分类与判断,从而可以减小背景光和有源干扰对激光近炸引信的影响,进一步提高了激光近炸引信的抗干扰能力.同时对引信中弹体旋转、测距信息加密等关键技术问题进行了分析和讨论.The laser proximity fuze is liable to the influence of background light and active interference.To improve the anti-interference performance of laser fuze,the polarized properties of laser were applied in the laser fuze in this study.By analyzing the polarized properties of laser,the target and the distance information was obtained.According to the polarized properties of scattering light,the laser fuze distinguished the target from the background,which reduced the influence of background light and active interference.Some other key technologies of laser fuze,such as rotation of bomb and information encryption,were also studied.
