本文致力于发展对合成孔径雷达的时延干扰技术。传统的时延回波干扰在经过合成孔径雷达系统后只能得到一点或一条线的虚假成像，不能有效地保护分布式目标。提出了一种改进的时延回波干扰方式--时延脉冲间抖动回波干扰(TDIJEJ)。理论分析和仿真表明，这种干扰可以获得SAR的快速时间匹配处理增益，从而降低干扰功率需求，并产生干扰条带输出，以达到保护分布式目标的目的。
This work is concerned with developing the timedelay-based jamming technology against SAR. Traditional time-delay echo jamming can only get a point or a line false imaging when through the SAR system, which can't protect distributed targets. This paper presents a modified time-delay echo jamming style, Time-delay Inter-pulse Jitter Echo jamming (TDIJEJ). The theoretic analysis and simulation show that this interference can obtain the fast time matched processing gain of SAR thus deduce the jamming power requirement, and generate a jamming swath output for the purpose of protecting distributed targets.
