摘　　要：针对线性调频脉冲压缩雷达回波信号距离和多普勒频率存在耦合这一特点,在固定移频干扰的基础上,提出了2种改进的移频干扰方法——正弦波移频干扰和随机移频干扰。对于2种改进的移频干扰,分别仿真分析了不同参数取值情况时的干扰效果。Aiming at the characteristic that there is coupling between the echo signal range and Doppler frequency of linear frequency modulation pulse compression radar,this paper puts forward two kinds of improved frequency-shift jamming methods——sinusoid frequency-shift jamming and random frequency-shift jamming based on fixed frequency-shift jamming,and respectively analyzes the jamming effects under different parameter values through simulations for two improved frequency-shift jamming.
