摘　　要：对DRFM(数字射频存储器)干扰设备原理进行了介绍,通过控制DRFM的读出时间,以模拟运动目标回波的时间延迟,在分析了转台模型成像原理的基础上,提出了利用DRFM对逆合成孔径雷达转台模型进行假目标欺骗干扰的方法,经过理论推导和计算机仿真,结果证明了该方法可以有效干扰ISAR转台模型成像效果。The principles of Digital Radio Frequency Memory（DRFM）jamming equipment are firstly introduced in this article. By controlling the time that DRFM read out,the time delay of moving target echo is simulated. On the basis of analyzing the principle of rotatable imaging model, the method using DRFM for false target deception jamming against Inverse Synthetic Aperture Radar（ISAR） rotatable model is proposed. Through theoretically deduction and computer simulation, the results testify that this method can effectively jam the imaging effect of ISAR rotatable model.
