敌我识别系统对抗技术研究

摘要

IFF system plays an important role in modern wars.The technical parameters of IFF countermeasure system are analyzed and the sensitivity needed for IFF reconnaissance system is given.Aiming at weaknesses of IFF systems,feasibility of IFF jamming is analyzed.Suppression jamming,deception jamming and smart jamming are then thoroughly discussed.Finally,jamming effect of suppression jamming is theoretically computed.%敌我识别系统在现代战争中具有重要地位。分析了敌我识别对抗系统的技术指标需求,通过仿真给出了侦察IFF信号的系统灵敏度。针对IFF系统存在的弱点,分析了敌我识别干扰的可行性,探讨了压制性干扰、欺骗性干扰和灵巧干扰的方法。最后对噪声压制干扰的干扰效果进行了理论计算。
