摘　　要：针对线性调频雷达信号距离和多普勒频率存在强耦合的特点,提出了多种移频干扰技术,并对不同移频干扰方法的效果进行了分析和仿真,该研究结果可指导干扰信号的波形设计。同时也分析了移频干扰对相位编码雷达信号的干扰效果,并对典型巴克码信号进行了仿真分析,仿真结果表明,移频干扰不适用于相位编码雷达信号。Aiming at the characteristics that the distance and the Doppler frequency of linear frequency modulation radar signals are strongly coupled,this paper proposes a variety of frequency shift jamming technologies,and analyzes and simulates the effects of different frequency shift jamming methods.The results of this study can guide the waveform design of jamming signal.At the same time,this paper also analyzes the jamming effect of frequency shift jamming on phase coding radar signals,simulates and analyzes the typical Barker code signal.The simulation results show that frequency shift jamming is not adapted for phase coding radar signals.
