摘　　要：为实现对采用线性调频信号的相控阵雷达灵活有效干扰,解决稀疏与密集多假目标干扰信号快速生成问题,将卷积调制和移频调制有机结合,给出了一种移频卷积复合调制的相控阵雷达干扰方法.理论分析与仿真结果表明,该方法可充分利用卷积与移频调制的各自优点,不仅能在真实目标前后或周围快速生成稀疏多假目标,而且通过适时调整卷积脉冲串的重复周期,亦可快速生成密集假目标干扰并将真实目标"淹没",形成了类似压制的干扰效果.In order to realize the effective jamming of phased array radar using linear frequency modulation(LFM)signal and acquire the capability of fast generating jamming signals of sparse and dense multiple false targets,this paper organically combines convolution modulation with frequency shift modulation to present a phased array radar jamming method with hybrid modulation of convolution and frequency shift.Theoretical analysis and simulation result indicate that the proposed method can make full use of the advantages of convolution and frequency shift modulation,which can not only generate sparse and multiple false targets before and after the real target or around it,but also generate dense false target interference rapidly so as to“submerged”the real target,forming the interference effect similar to suppression through timely adjusting the repeated period of the convolution pulse train.
