Abstract

Aimed at the problem that the correlation between the false targets (FTs) amplitudes among the receivers of the multi-static radar system (MSRS), a cooperative deception jamming method with multiple jammers based on periodic multiple phases modulation (PMPM) is proposed in this paper. In the distributed jammer system, each jammer adopts the PMPM jamming method with different parameters, and then jointly transmits the beam to forward the jamming signal. Finally, the amplitude of the FTs between the receivers is affected by the combination of the azimuth angle and the phase modulation coefficient, which breaks the correlation of the FTs amplitude between the receivers. Aiming at the problem of obtain stable and optimal jamming effects, a jamming modulation parameters optimization method based on genetic algorithm is proposed, the detection probability of the physical targets (PTs) is always 0%. The effectiveness of the proposed method is verified by simulation.
基于周期多相调制的多基地雷达欺骗干扰
针对多静态雷达系统接收机间虚目标(FTs)幅值的相关性问题,提出了一种基于周期多相调制(PMPM)的多干扰机协同欺骗干扰方法。在分布式干扰系统中,各干扰机采用不同参数的PMPM干扰方式,然后联合发射波束转发干扰信号。最后,接收机间的傅里叶变换振幅受方位角和相位调制系数的共同影响,从而打破了接收机间傅里叶变换振幅的相关性。针对获得稳定最优干扰效果的问题,提出了一种基于遗传算法的干扰调制参数优化方法,该方法对物理目标的检测概率始终为0%。仿真结果验证了该方法的有效性。
