摘要：

主瓣距离欺骗式干扰对真实目标的估计精度以及目标跟踪的准确性都会产生极大的影响。针对主瓣距离欺骗式干扰抑制问题, 基于脉冲编码-多输入多输出(element pulse coding-multiple input multiple output, EPC-MIMO)雷达, 针对主瓣距离欺骗式干扰的脉冲重复频率(pulse repetition frequency, PRF)大于等于两个发射脉冲重频情况, 提出了一种抑制主瓣距离欺骗式干扰的算法。在EPC-MIMO雷达主瓣距离式干扰抑制算法中, 首先利用线性调频信号对雷达系统中雷达发射-接收通道的信号进行幅相误差校正; 其次通过分析雷达回波中真、假目标的脉冲信号差异, 对EPC-MIMO雷达的回波进行匹配分离, 从而获得转发式干扰的规律; 最后对雷达回波的筛选达到抑制假目标的目的。通过对雷达实测数据的分析, 验证了该方法能够有效解决主瓣距离欺骗式干扰抑制问题, 提升雷达在复杂电磁环境的抗干扰性能。

Abstract:

The mainlobe distance deceptive jamming will have a great impact on the estimation accuracy of real targets and the accuracy of target tracking. Based on element pulse coding-multiple input multiple output (EPC-MIMO) radar, an algorithm for suppressing mainlobe range deception jamming is proposed when the pulse repetition frequency (PRF) of mainlobe range deception jamming is greater than or equal to the repetition frequency of two transmitted pulses. In the mainlobe range jamming suppression algorithm of EPC-MIMO radar, firstly, the linear frequency modulation (LFM) signal is used to measure and correct the amplitude and phase errors of the transmitter receiver channel in the radar system. Secondly, by analyzing the pulse signal difference between the true and false targets in the radar echo, the echo of EPC-MIMO radar is matched and separated, so as to obtain the law of repeater jamming; Finally, the radar echo is screened to suppress false targets. Through the analysis of radar measured data, it is verified that this method can effectively solve the problem of mainlobe range deception jamming suppression and improve the anti-jamming performance of radar in complex electromagnetic environment.

Key words: mainlobe range deceptive jamming, element pulse coding multiple input multiple output (EPC-MIMO) radar, amplitude and phase error correction of radar transmit receive channel signal
