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 near-fuze is easy to be affected by all kinds of active interferences.On the basis of studying the principle that the laser’s polarization state can distinguish the target from the background, the laser’s polarization property is applied to the laser fuze.By analyzing the polarization of the laser beam To achieve the purpose of distance measurement, target classification and information confidentiality.During the work, fuze can classify and judge the polarization orientation of laser scattering echo signal according to the target and background, so that the background light and active interference pair can be reduced Laser fuze near the fuze to further improve the anti-jamming capability of the laser near-fuze.At the same time, the key technical issues such as fuselage rotation fuze, ranging information encryption and so on are analyzed and discussed.
