转发式干扰对SAR的干扰仿真

摘要

针对SAR的技术特点,对SAR的干扰措施做了简要概述,重点介绍了转发式干扰的信号模型,在此基础上,利用SAR常用的两种信号处理方法对转发式干扰做了成像仿真,得出了转发式干扰对这两种算法的干扰效果。%According to technical features of synthetic aperture radar(SAR),jamming measures against SAR is summarized;signal module of repeater jamming is introduced in detail.Imaging simulation of repeater jamming is conducted by way of two signal processing algorithms generally used by SAR,jamming effect of repeater jamming against these two algorithms is obtained.
