【摘要】 本论文围绕一个具体机载吊舱干扰模拟源项目进行。重点讨论有源压制干扰方式和欺骗干扰方式,并对干扰技术的实现和干扰信号的产生做了深入研究。在有源压制式干扰中,本论文主要讨论了调频噪声干扰,并着重讨论了基于瞬时测频(DIFM)的快速数字引频技术。基于DIFM快速数字引频技术的实现,在减少引导时间和提高引导精度方面具有一定优势。在欺骗式干扰方式中,本论文主要讨论了基于数字射频存储器(DRFM)为核心的欺骗干扰技术的实现。DRFM采用10比特幅度量化体制,有效减小寄生信号的影响,最大限度的保持干扰信号与接收的雷达信号特征一致。在干扰吊舱系统控制软件控制下,能有效的实施距离欺骗干扰、速度欺骗干扰、距离-速度欺骗干扰、多假目标干扰以及多普勒噪声干扰。本论文设计的雷达干扰模拟源在机载干扰吊舱系统中使用,可以模拟多种机载干扰吊舱的功能,实施大功率噪声压制干扰和欺骗干扰。在和平年代,该干扰吊舱系统主要用于某基地武器系统抗干扰性能试验测试,也可以用于部队官兵进行雷达抗干扰适应性训练。该系统在外场进行多次试验,取得良好效果。更多还原

【Abstract】 This paper focuses on a specific project of the airborne jamming pod interference source simulation. This paper has mainly discussed the active jamming and the deception jamming, and made some research on the realization of the technique of interference and the disturbance signal generation. In the active jamming, this thesis mainly discusses the FM noise interference, emphatically the fast digital led frequency technology based on instantaneous frequency measurement (DIFM), which has an advantage of reducing lead time and improving the frequency guided precision.Under the deception jamming mode, it mainly discusses the implementation of deception jamming technology based on digital radio frequency memory (DRFM) as the core. DRFM using 10 bits amplitude quantification system, can reduce parasitic signal effectively, and maximize the consistence of characteristics of the jamming signal and receiving radar signal. When controlled by software in a nacelle interference system, it can realize distance deception jamming, speed deception jamming, distance-speed deception jamming, many false target interference and Doppler noise interference effectively.The designed radar interference simulator in an airborne jamming pod can simulate various functions about the airborne jamming pod and carry out the high-power noise jamming and deception jamming. In time of peace, the jamming pod system is mainly used in a weapon system for anti-jamming performance tests. It can also be used for officers and soldiers to do radar anti-interference trainings. Finally, the test results of outfield proved it effective.更多还原
