一种有效的线性调频雷达干扰技术

A Kind of Effective Jamming Technique for LFM Radar

根据线性调频雷达发射信号的特点,提出一种新的干扰技术——锯齿波调频干扰,即干扰机对接收到的雷达照射信号附加锯齿波频率调制,将调频结果放大之后转发出去。根据调制参数不同,这种干扰可以产生假目标欺骗和覆盖干扰。该技术要求较低的干扰功率。理论分析和计算仿真验证了这一新技术的有效性。

According to the characteristics of the linear frequency modulation（LFM） radar signals, this paper puts forwards a new iamming technique sawtooth wave frequency modulation（FM） jamming,that is, the jammer adds the sawtooth wave frequency modulation to the received radar signal,and transmits the FM result after amplifying it. This jamming can produce false targets deception jamming and cover jamming according to the modulating parameters. This technique requires lower jamming power. This paper iustifies the efficiency of the new jamming technique by theoretical analysis and computer simulation.
