摘　　要：针对采用线性调频信号的脉冲多普勒相参雷达导引头的遮盖性干扰样式,提出了一种灵巧噪声干扰设计方法。该方法可利用处理增益,降低对干扰功率的要求;而且既有假目标欺骗性干扰效果,又有噪声遮盖性干扰效果。设计了灵巧式噪声干扰产生的波形,并通过建模仿真说明了灵巧噪声干扰的有效性,且性能明显优于普通射频噪声干扰。Aiming at covering jamming mode of pulse doppler radar seeker using LFM signal, a smart noise jamming design method is proposed. This method can reduce jamming power with advantage of processing gain, produce covering and deception jamming effects. Designs the wave form of smart noise jamming, proves the effect of smart noise jamming through simulation. The smart noise jamming is more effective than radiofrequency noise jamming.
