摘　　要：为了评价信息作战条件下雷达网的抗干扰能力,分析了影响雷达网抗电子干扰能力的因素,给出了量化方法。在模糊物元分析的基础上,结合欧氏贴近度的概念,提出了基于欧氏(欧几里得)贴近度的模糊物元分析法。在对雷达网抗干扰能力进行评价时,以雷达网的各项评价指标及其相应的模糊量值构造复合模糊物元。通过计算与标准模糊物元之间的欧氏贴近度,实现了对雷达网抗干扰能力的评价,为雷达网抗干扰能力评价提供了一个新的方法。In order to evaluate the anti-jamming performance of radar nets, factors affecting the radar nets ECM capacity were analyzed and measurement methods were supplied. A new approach was put for- ward to construct the compound fuzzy matter element, based on the fuzzy matter element, the concept of Euclid approach degree and the index of radar nets and their fuzzy value. Through calculating Euclid ap- proach degree between the fuzzy matter element and the standard （the best） fuzzy matter element, this new approach for evaluation of the radar net capability of anti-jamming was presented.
