摘　　要：针对常规间歇采样转发干扰存在的问题,提出了一种移频调制非均匀重复转发的干扰样式,该样式通过对采样信号施以多普勒频移调制和非均匀转发,可在不改变干扰系统瞬时发射功率的前提下,同时兼有群体压制干扰和欺骗干扰的双重效果。能够有效的降低硬件设计的复杂程度,具有工程实现的可行性。仿真实验表明:干扰效果取决于采样脉宽、转发脉宽、采样周期以及移频函数的选取,实际运用时需根据具体作战对象的类型和工程实现的难度进行综合考虑。Aiming at the problem of conventional intermittent sampling jamming,a non-uniform repetition jamming pattern of frequency shift modulation is proposed. It performs Doppler frequency shift modulation and non-uniform transmission on the sampled signal,and achieves the dual effects of suppression jamming and deception jamming without changing the instantaneous transmission power of the jamming system. It can effectively reduce the complexity of the hardware design and has the feasibility of engineering implementation. Simulation experiments show that the jamming effect depends on the sampling pulse width,the width of the forwarding pulse,the sampling period,and the selection of the frequency shift function. When it is actually used,it needs to be comprehensively considered according to the type of the specific combat object and the difficulty of the project implementation.
