摘　　要：合成孔径雷达(SAR)是一种高分辨率成像雷达,具有良好的对地侦察探测能力。在电子战应用中,对SAR的干扰特别是成像欺骗干扰研究具有迫切的现实应用需求。首先建立了针对SAR雷达的成像欺骗干扰模型,根据干扰模型给出了具体的欺骗干扰流程。然后采用成像算法进行了仿真闭环验证,仿真结果表明了算法模型的有效性。最后,简单分析了该成像欺骗方法在实际工程实现时要注意的问题。Synthetic aperture radar（SAR）is a kind of high resolution imaging radar which has excellent detection and reconnaissance of targets on earth.The research on SAR jamming especially imaging deception jamming methods are urgent needed in electronic war.Based on SAR jamming geometry model and radar waveform,the signal model of SAR deception is presented firstly.The work program of SAR deception jamming is proposed also.The simulation result shows that the method is validated through SAR imaging algorithm.Lastly,several problems are simply analyzed when this method is implemented in practical engineering.
