| 摘 要： | 针对传统干扰技术对PD雷达干扰的不足,噪声干扰对干扰机功率要求高,欺骗干扰产生的干扰数目单一,基于当前对抗先进体制雷达的手段——DRFM,对PD雷达干扰进行研究。通过将截获的雷达信号存储、处理,按程序设定的转发间隔重复读出当前采样信号并转发,产生了多个距离欺骗假目标;通过对每次转发干扰进行频率调制,产生了包含距离速度欺骗的一系列假目标;并经过Matable仿真验证了在PD雷达窄带滤波器中,出现多个距离或速度欺骗假目标。并通过仿真验证了干扰的有效性。

| Abstract: | Aiming at the insufficient noise jamming on pulse Doppler(PD) radar,the requirement of high jamming power and few deceptive jamming signals of traditional interference,based on digital radio frequency memory(DRFM),a means against current advanced radar,jamming on PD radar is studied.Multiple distance-deceptive false targets are generated by repeatedly reading the sampling signals according to the repeating interval and transmitting them after the storage and process of the intercepting radar signal,and a series of distance-deceptive and speed-deceptive false targets are generated through the frequency modulation on transmitting interference.The results of experiments and simulations prove the effectiveness of the interference designed. |
