摘要
转发式干扰是针对合成孔径雷达的一种有效干扰手段。该文介绍了合成孔径雷达转发式干扰的原理,讨论并分析了虚假目标的生成位置以及虚假目标的成像质量。并针对实际工程中遇到的信号处理时间的问题,研究了将虚假信号延迟转发的可行性。通过仿真验证了由上面的分析所得出的结论,并介绍了这种转发式干扰在实际中的应用。
Repeater jamming is an effective means to Synthetic Aperture Radar（SAR）. In this paper, the principle of the SAR repeater jamming is introduced, and the positions and imaging quality of the illusory targets are also discussed. Meanwhile, considering the signal processing time in the practical engineering, the feasibility of the received signal＇s delay repeating is also studied. Simulation result confirms the conclusions derived from above, and a practical use of the repeater jamming is introduced at last.
