摘要
雷达敌我识别系统用来识别雷达发现目标的敌我属性,它的基本原理是询问机发射射频脉冲询问信号给应答机,应答机收到后自动发回应答信号完成敌我识别;雷达敌我识别干扰则是利用己方的雷达敌我识别对抗装备对敌方的雷达敌我识别系统实施电子干扰的作战行动。文章通过阐述基本工作原理、分析典型信号特征,介绍了雷达敌我识别系统;针对其存在的弱点,分析了雷达敌我识别干扰的可行性;结合已有研究成果和可行性分析,探讨了压制性干扰、欺骗性干扰和灵巧干扰的方法,对雷达敌我识别对抗技术的深入研究具有一定的意义。
Radar IFF system is used to identify the friend or foe property of the radar target. Its basic principle is the procedure that interrogator launches RF pulse signals to transponder and then transponder sends back the reply signals automatically. Taking advantage of the radar IFF counter- measure equipment, radar IFF jamming is the military operation which is carried out by electronic interference on foe＇s radar IFF system. By expatiating on the basic working principle and analyzing the typical signal characteristics, radar IFF system is introduced; for its weaknesses, the feasibility of radar IFF jamming is analyzed; combining with the research production and the feasibility analy- sis, the methods of blanket, deception and smart jamming are discussed in depth. It＇ s meaningful and helpful to study on radar IFF countermeasure technique further.
