Abstract：Aimed at the problems that the spatial distribution of interrupted-sampling and repeater jam-ming is not ideal,and the traditional frequency shift methods are hardly utilized for dealing with character-istics of interference,a spectrum spread and compression(SSC)algorithm is used to change this situation. This paper analyzes the expression of fake target based on ambiguity function.Then a SSC algorithm is used to produce advance interferences.The theory and simulation results show that this proposed method is able to improve the spatial distribution of this kind of interference.What's more,compared with the di-rect frequency shift,this method can be effectively confronted by the frequency modulation slope agility ra-dar without prior knowledge.
