摘要 转发式欺骗干扰能够利用与雷达信号的强相干性的特点进入雷达,形成虚假航迹,从而影响战场评估。针对此问题,本文提出了一种新的利用模糊评判的抗欺骗干扰方法。该方法首先提取回波的幅度、干扰误差角特征,利用模糊评判对欺骗干扰进行识别,有效提高了识别效果;其次将得到的隶属度用于3/4逻辑霍夫变化航迹起始以及概率数据互联航迹滤波算法的改进,抑制虚假目标在雷达形成航迹;最后,仿真实验表明本方法能够有效地抑制欺骗干扰,确保雷达对真实目标的跟踪。 The repeat-deception-jamming form false tracks using the strong coherent signal with radar signal and impact assessment of the situation. For this problem, a novel anti-deception jamming method is proposed in this paper. First, the method uses fuzzy evaluation with extractions of the features of amplitude and jamming signal error angle to improve the identify effect of deception jamming; Then put the membership degree into the 3/4 logical hough transformation track initiation method and probabilistic data association filter track filtering method to suppress the false targets in radar tracks ; Finally the simulation results show that the method can suppress the deception jamming validity and ensure radar tracking of real targets.
