| 摘 要： | 本文提出一种新的合成孔径雷达(SAR)干扰方法:SAR二维余弦调相转发散射波干扰.该方法将SAR二维余弦调相转发干扰同散射波干扰结合,利用二维余弦调相转发干扰实现多假目标干扰,再通过散射波干扰使干扰回波携带真实目标的散射信息,二者的结合相得益彰,为实现多假目标干扰和假目标携带真实目标散射信息提供了一种可行途径,实现了对SAR在时域、频域和极化域都较为逼真的多假目标欺骗干扰.理论分析和仿真实验验证了该干扰方法的可行性和有效性.

| Abstract: | A new method of SAR jamming is proposed: the 2-D cosinusoidal phase-modulated repeater scatter-wave jam-ruing. This jamming takes advantages of both the 2-D cosinusoidal phase-modulated repeater jamming which can form multi-false targets,and the scatter-wave jamming which can make the jamming echo take the real targets' scattering information. The combina-tion complements each other, provides a feasible approach of achieving the multi-false targets jamming and the false targets take the real targets' scattering information, and realizes the vivid multi-false targets jamming in time, frequence and polarization domain. Its feasibility and validity are proved by theoretical analysis and simulation. |
