| Abstract: | 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. |
