摘要
根据MIMO雷达工作特性,提出了针对单基地MIMO雷达的干扰方式,详细分析了其工作原理。在此干扰方式的基础上,针对采用线性调频信号的单基地MIMO雷达,推导了卷积干扰对其进行干扰的数学模型,分析了干扰信号的时频特性。理论分析证明,卷积干扰对LFM-MIMO雷达具有显著的干扰效果,而且采用的卷积信号不同,可以实现对MIMO雷达的假目标欺骗干扰和噪声覆盖干扰两种效果。最后,仿真实验表明理论分析的正确性。
A new jamming method to counter the mono-static MIMO radar is proposed according to work property of the MIMO radar, and working principle is analyzed in detail. The mathematical mod- el of convolution jamming against mono-static LFM-MIMO radar is derived, then time-frequency prop- erty of jamming signals are analyzed. Theoretical analysis shows that the convolution result is retrans- mitted, and then false targets deceptive jamming and noise cover jamming are produced with different convolution signals. Lastly the validity of theoretical analysis is validated with the computer simula- tion.
