摘　　要：随着数字射频存储技术的发展,转发式干扰逐渐应用于现代战场,采用多无人机对敌方组网雷达实施航迹欺骗干扰成为一种新型对抗手段。而在干扰过程中,由于设备精度不足产生的时延误差将对同源检验结果产生影响。为了提高干扰成功率,估算时延误差可接受的边界值具有一定现实意义。首先,分析了时延误差对干扰效果的影响;而后,结合“AND”思想和空间分辨单元的同源检验方法,给出了有效干扰的判定条件;最后,基于不同时延误差分布模型完成边界值求解。仿真结果表明:服从不同分布的时延误差模型对可接受的误差边界值具有不可忽视的影响,且时延误差边界值与预设虚假目标到雷达距离成正比。With the development of digital radio frequency memory technology,repeater jamming is gradually applied to the modern battlefield.Using multiple UAVs to implement track deception jamming on enemy networked radar has become a new countermeasure method.In the jamming process,the delay error caused by insufficient equipment accuracy will affect the homology test results.In order to improve the success rate of interference,it is of practical significance to estimate the boundary value of acceptable delay difference.Firstly,the influence of delay error on the interference effect is analyzed,and then the judgment conditions of effective interference are given by combining the thought of"AND"and the homology test method of space resolution cell.Finally,the boundary value is solved based on different delay error distribution models.The simulation results show that the delay error models with different distributions have a significant effect on the acceptable error boundary values,and the delay error boundary values are proportional to the preset distance from the false target to the networked radar.
