一种星载SAR图像欺骗式干扰技术

A technology of deceiving jamming for space born SAR images

星载合成孔径雷达(SAR)干扰技术研究在国防、军事、现代化战争中有着特别重要的意义和应用,是当前电子对抗技术中的前沿和热门研究课题.目前,SAR欺骗式干扰是最受重视的研究,其中,虚假目标式干扰又是欺骗式干扰的研究主题.传统的虚假目标式干扰是采用修改目标后向散射特性的方法来实现欺骗式干扰.然而这种方法的运算量较大,耗时较多.为此,我们提出采用构造欺骗式干扰系统脉冲响应函数的技术来生成虚假目标实现欺骗式干扰.这种技术的优点是计算量较小,速度较快.

The study of space borne synthetic aperture radar （SAR） jamming technology is particularly significant and applicable in national defence, military affairs, and contemporary wars, and is a cut edge and hot subject in up-to-date electronic warfare. Today, deceiving jamming of SAR is the most recognized study, and of which the fake target jamming is a main topic. The traditional method of fake target jamming is to modify the back forwards reflection parameters of targets and perform deceiving jamming. However, the jamming runs consumptively in computation and time. Hence, a technology of constructing a pulse response function of jamming system is proposed in this paper to generate fake targets and perform deceiving jamming. The advantage of this technology is less computation and higher speed than the traditional method.
