摘要
未来的合成孔径雷达(SAR)分辨率越来越高,单一雷达的成像模式越来越灵活多样,大场景、多模式和高分辨是电子对抗面临的环境,相应的干扰技术应及时跟进。介绍了现阶段雷达成像系统的研究状况,在此基础上介绍了传统的雷达成像干扰技术和新型的成像干扰方法,并着重对有源干扰中的卷积调制干扰的改进算法、微动调制干扰、间歇采样转发干扰和复合调制干扰进行了分析。对SAR干扰效果评估做了简要分析,并对成像干扰技术做了展望。对雷达成像干扰技术的研究具有一定的借鉴意义。
In the future,the SAR will have higher resolution,and a single radar can realize multiple kinds of imaging modes.Large-area,multi-mode and high-resolution will be the trend of SAR,and simultaneously the countermeasures should develop.Firstly,this paper introduces researches on radar imaging system.Then some conventional SAR imaging and novel SAR imaging jamming methods are illuminated,with the emphasis on convolutional modulation,micro-motion modulation,intermissive sampling repeater and compound modulation jamming techniques.Next,some evaluations on SAR jamming are introduced.In the end,some technical trends of SAR jamming are predicted.This review will be a reference to researches on SAR jamming.
