摘要
针对抗波门拖引干扰现有理论研究的不足,结合现代欺骗式干扰机的结构特点和干扰信号的产生机理及对具体雷达接收机的作用机理,分析干扰信号进入雷达系统后雷达接收回波信号的特征变化;提取接收信号统计特征及细微特征检测有无干扰;并根据干扰过程中回波信号与干扰信号相互作用的规律及时变特征,研究了干扰信号识别的理论模型,形成了基于过程的波门拖引干扰子类型的识别方法,为进一步提高雷达系统抗干扰能力提供理论基础。仿真实验证明该方法有较高的识别率。
Aiming at the insufficient existing fundamental,combined with the structure characteristic of deception jammer,generation mechanism of gate-pull jamming and its action mechanism to the concrete radar receiver,the variation of radar receiving signal＇s characteristic is anaylzed when jamming enteres the system.The statistical and fine fetures of the receiving signal is extracted to detect jamming,and theoretical model of jamming identification is studied according to the interaction and time-varying characteristic between the real echo and jamming in the process of gate-pulling.A gate-pull jamming subtype identification approach is formed based on processing which provids theoretical basis to further improve radar system anti-jamming ability.In the end,experiments show that this method is feasible and has comparatively better correction identification ability.
