摘　　要：针对传统间歇采样干扰存在的缺点:脉压结果呈现规律性,易于被多体制雷达识别剔除;生成的干扰落后真实目标。本文研究了一种基于频移调制的非均匀间歇采样干扰,其可以对采样信号施加多普勒频移以及非均匀转发,其干扰后的脉压结果分布于真实目标两侧,并且破坏原有均匀采样的规律性。仿真实验表明,基于频移调制的间歇非均匀采样干扰和传统方法相比产生了较好的干扰效果和抗识别特性。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 modulation produce better interference effects and anti-recognition characteristics.
