For the shortcomings of traditional intermittent sampling interference:the pulse pressure results were regular and were easily eliminated by the new system radar recognition.In this article,a non-uniform intermittent sampling interference was studied based on frequency shift modulation,which can applied Doppler frequency shift and non-uniform forwarding on the sampling signal.The pulse pressure results after interference were distributed two sides of real targets and the disruption had regularity of uniform sampling.The simulation experiments showed that the intermittent non-uniform sampling interference and traditional methods based on frequency shift modula-tion produce better interference effects and anti-recognition characteristics.
