摘　　要：研究雷达模拟器目标威胁度的准确评估问题,是辅助操作手对空中目标进行打击的重要依据。威胁度普通雷达是难以探测的。由于目标的速度、距离等随机性强,具体数据难以确定。针对威胁度评估问题,多限于权重分析、聚类分析等方法,对难以确定的参数有较大依赖。为解决上述问题,提出应用效能指数的方法来确定未知目标对雷达阵地的威胁度,根据雷达能够获取的数据,得出判断矩阵,实现对雷达所测数据的分析,并评估目标的威胁度。上述方法可用于雷达模拟器,能够灵活地根据情况调整威胁度评估方法。实验结果表明,方法能够较好地在某些属性未知的情况下,可对目标威胁度进行准确评估,证明改进方法为威胁度评估提供了有效依据。Threat assessment evaluation of radar simulator is an important parameter for radar operator to assault air targets.However,at present,the researches on threat assessment evaluation are most limited in proportion analysis and clustering analysis.Especially,some methods are depended on target type that is almost impossible to ensure.This paper proposed a method of threat assessment evaluation,using an efficiency-index method to confirm threat level of unknown targets to the radar.Based on data acquire by radar,the estimation matrix was educed,the analysis of data from radar was actualized,and the threat assessment of target was evaluated.Using this method of radar simulator,we can adjust the arithmetic of threat assessment agilely.Experiment shows that the proposed method is capable of assessing unknown targets＇ threat level under the situation of some unknown attributes.
