Abstract In this paper, the general noise jamming, cheat jamming and a novel similar clutter jamming method are discussed. From the viewpoint of the jamming power, the precision of leading parameters and the jamming effect, the matched jamming is proposed after the theory analysis. Both the theory analysis and simulation, bring the same conclusion that the similar clutter jamming method based on the multidimensional digital modulation, matches the SAR’s receiver and possesses the similar statistical characteristic with the SAR background clutter. It can partly overcome SAR’s high processing gain and requires moderate precision of leading parameters. Therefore, it is the realizable jamming method presently.
