摘　　要：为了判别数字射频存储干扰机对防空雷达产生的虚假航迹,提出了将虚假航迹判别归结为速率差检测的方法并推导建立表达式。该方法结合真实目标与干扰机在防空雷达平面位置显示器上产生航迹的原理,从目标点迹间的速率变化情况进行分析。采用MATLAB编写了仿真和判别程序,并根据程序运行结果给出了判别门限,验证了方法的有效性,为判别航迹欺骗干扰提供了新的技术途径。In order to distinguish the false track produced by digital radio frequency memory to air surveillance radar,a novel method is proposed by analyzing the change of speed between points of the track.According to the different principles of generating track between true targets and jammer on radar plan position indicator display,the discrimination issue is determined to be the problem of speed difference detection,and the formula is deduced.MATLAB is used to write simulation and discrimination procedures for calculating the judge threshold,and the method is verified with the experimental results of simulation.This method can provide a new solution to distinguish the false track.
