Abstract: Besides the introduction of Synthetic Aperture Radar (SAR) Electronic Countermeasures (ECM)， the closely related aspects of SAR systems， Electronic CounterCountermeasures (ECCM) and the jamming evaluation are also reviewed as well. The typical jamming techniques are divided into two types as the traditional jamming methods and peculiar jamming methods， and are displayed one by one in detail. The development history of SAR jamming techniques are provided， where the development trend and the existing problems are induced. To make SAR ECM more effective， the jamming techniques trend towards coherent jamming complicatedly modulated jamming， multiple various jamming， and moving target jamming.
