旁瓣询问干扰下的敌我识别系统目标检测概率分析

Analysis on SSR IFF System＇s Target Detection Probability in Sidelobe Inquiring Jamming

敌我识别（IFF）系统在现代战争中占有极为重要的地位。文章介绍了二次雷达IFF系统的工作原理，针对IFF系统工作机理中存在的不足，分析了旁瓣询问干扰原理，从IFF系统的识别概率的角度，论证了旁瓣询问干扰能提高二次雷达IFF系统的应答占据概率，因而降低IFF系统的识别概率，从而达到干扰IFF系统的目的。

IFF system plays an important role in modem wars. In this paper, the principles of the IFF system are introduced. According to the disadvantage of the working mechanism of IFF system, a sidelobe inquiring jamming model is studied, from the study on the identification probability, it is proved that the sidelobe inquiring jamming can enhance the response occupied probability of SSR IFF system, so that can degrade the identification probability of IFF system, and to realize the pur- pose of the IFF interference.
