在对雷达抗干扰评估准则论述的基础上，分析了常用抗干扰评估方法的实质。仿真了抗干扰改善因子变化对雷达抗干扰性能的影响，验证了抗干扰改善因子的通用性和合理性，讨论了基于改进抗干扰改善因了的效能评估模型。最后给出典型组合抗干扰方法的抗干扰改善因子经验值。

Based on describing the model and criterion of ECCM capability evaluating, the paper analyze the essence of traditional ECCM methods, simulate the effect of EIF on radar ECCM capability. Applicability and rationality of EIF is proved, then it discusses the model of Radar ECCM Capability base on amended improve EIF. At the end, some typical ECCM methods value of EIF are given.
