摘　　要：为解决单干扰机无法对干涉逆合成孔径雷达(Interferometric Inverse Synthetic Aperture Radar,InISAR)产生三维干扰效果问题,结合雷达目标微多普勒效应提出了基于双干扰机的InISAR三维干扰方法。首先介绍了InISAR成像原理,同时分析了单站干扰无法对InISAR产生三维干扰效果的原因。随后根据微动假目标模板讨论了两部干扰机内干扰信号合成方法,计算了两干扰信号在InISAR各个天线通道内分别叠加产生的实时变化的干涉相位,并给出了微动假目标模板经成像处理后产生的虚假高程信息。最后通过仿真结果证明,该方法能够实现对InISAR的三维干扰。In order to solve the problem that single jammer can't produce three-dimensional(3-D)jamming effect on interferometric inverse synthetic aperture radar(InISAR),a method capable of generating 3-D microDoppler modulation jamming of InISAR using double jammers is proposed based on the micro-Doppler effect of radar targets.Firstly,the principle of InISAR imaging is introduced,and the reason that why single jammer can't produce three-dimensional(3-D)jamming effect on InISAR is analyzed.Then the procedures of synthesizing jamming signals in two jammers are discussed according to the template of false micro-motion targets.After that,the real-time interferometric phase of two jamming signals produced in the InISAR antenna channels are superimposed,and the false elevation information of the false micro-motion targets can be generated after the image processing.Finally,the theoretical analysis and simulation results show that the method can realize the three-dimensional micro-Doppler modulation jamming of InISAR.
