摘　　要：在杂波背景下,传统的自卫转发式航迹假目标欺骗干扰识别方法的正确识别率较低,且利用单一信号特征鉴别真假目标的正确鉴别率较低。针对此问题,提出了一种新的抗自卫转发式航迹假目标欺骗干扰技术。首先,使用常规多目标跟踪算法消除杂波的影响,然后利用基于目标状态估计的角度检验和N/M逻辑准则判断雷达是否遭受自卫转发式航迹假目标欺骗干扰。若存在干扰,则提取目标信号的幅度和相位量化信息,使用多级模糊综合评判对真假目标进行联合鉴别。该技术对自卫转发式航迹假目标欺骗干扰正确识别率较高,能有效剔除形成稳定航迹的假目标。仿真结果验证了该技术的可行性和有效性。In the presence of clutter, the accurate recognition rate for traditional self-protection repeating track false-target deceptive jamming is low, and the accurate identification rate of distinguishing true or false targets using a single signal characteristic is also low. Aiming at the problems, a new technique of anti self-pro- tection repeating track false-target deceptive jamming is proposed. The conventional multi-target tracking algo- rithm is used for eliminating the influence of clutter firstly. Then the angle test based on target state estimation and the N/M logic rule are used to determine whether radar is jammed by self-protection repeating track false- target deceptive jamming. If the jamming exits, the amplitude and phase quantization information of the target signal is extracted, then the multi-level fuzzy comprehensive evaluation is adopted to distinguish true or false targets jointly. The technique can recognize self-protection repeating track false-target deceptive jamming with the high accurate recognition rate, and can eliminate the false targets which form the stable track. Simulation results verify the feasibility and validity of the proposed technique.
