中文摘要：

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。

英文摘要：

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 accord- ing 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 fre- quency modulation on transmitting interference. The results of experiments and simulations prove the ef- fectiveness of the interference designed.
