摘　　要：SAR干扰一直是研究的热点。针对传统对SAR的弹射干扰的不足,提出了基于延时叠加弹射式干扰的方法,并进行了理论推导和仿真研究。仿真结果表明:延时叠加弹射式干扰形成的干扰图像可以有效地覆盖整个目标区域,获得非常好的干扰效果。Synthetic aperture radar(SAR)jamming has always been a research hotspot.Aiming at the shortcomings of traditional rebound jamming to SAR,this paper proposes a method based on delay superposition rebound jamming,and performs the theoretical derivation and simulation research.The simulation results show that the jamming image formed by delayed superimposed rebound jamming can cover the whole target area effectively and obtain very good jamming effect.
