提出了一种改进的合成孔径雷达散射波干扰方法。干扰器调整被拦截SAR信号的时延和相位。然后，创建一个虚假的场景，为某一区域提供有效的保护。干扰功率比弹幕干扰低，计算复杂度比直接路径欺骗干扰低。在分析散射波干扰性能的基础上，提出了延迟重传的脉冲重复间隔和调制中心移位作为扩大干扰面积的改进措施。
This study presents an improved scattered wave jamming method for synthetic aperture radar (SAR). The jammer adjusts the time-delay and the phase of the intercepted SAR signal. Then, a false scene is created to provide an effective protection for a certain area. It requires a lower jamming power than barrage jamming and has less computational complexity than direct-path deception jamming. Based on the performance analysis of scattered wave jamming, pulse repetition intervals to delay retransmission, and a modulation centre shift are proposed as improvements to enlarge the jamming area.
