对合成孔径雷达的转发式扫频干扰技术研究
Research on SAR Repeater Sweep Jamming Technology
摘要
Abstract
The jamming technology of synthetic aperture radar (SAR) is studied systematically. Based on the detailed theatrical analysis and simulation of the cosine repeater jamming and the phase covering camouflage jamming,a new method is proposed for SAR jamming, which is the repeater sweep jamming. The method modulates sweep frequency signal SAR echo by repeater, and it makes SAR echo not be compressed in range domain, so that this method has a potential to disturb auto focus algorithm. Theoretical analysis shows these methods can effectively jam SAR in the condition of low JSR to make it not image and protect distributed important target. Finally, these methods are proved effective and feasible by simulation of car model.关键词
