摘　　要：当前先进的跟踪雷达普遍采用自动跟踪系统,为了降低或破坏跟踪雷达效能,国内外专家提出了波门拖引干扰,但是对于这种干扰样式的效果评估鲜有研究。鉴于此,对距离波门拖引干扰效果评估进行了研究。首先介绍了距离波门拖引的干扰机理,通过对距离波门拖引过程的分析,建立了拖引方案评估指标和评估模型;然后运用评估模型对匀速拖引和匀加速拖引两种拖引方案进行了评估,通过仿真计算得到了一些有意义的结论,并就距离波门拖引方案设计给出了一点建议。At present, the advanced tracking radar always adopts auto-tracking system. In order to reduce or destroy the efficiency of tracking radar, the gate pull off countermeasure is presented by experts at home and abroad,but the effectiveness evaluation of this jam style is seldom studied. So the effectiveness evaluation of Range Gate Pull Off（RGPO）is studied in this paper. At first the technology of RGPO is introduced, the index factors and the model of RGPO design evaluation are presented by analyzing the process of RGPO, and then the two RGPO designs of velocity and acceleration pull off are evaluated by the model of RGPO design evaluation. With the help of simulation computation, some importance conclusions are considered and the suggestions of RGPO design are given.
