摘　　要：为评估对主动雷达导引头的干扰效能,结合导引头工作原理和功能特性,运用模糊数学理论,构建了对雷达导引头干扰效能进行评估的指标体系,建立了二级模糊评判模型,采用正态分布形式构造隶属函数,并利用指数标度的层次分析法(AHP)确定各因素的权重,使得判断矩阵的一致性指标得到改善,实现对雷达导引头的量化评估。最后选择噪声干扰为例进行模糊综合评判,实例分析结果表明该雷达导引头干扰效能模糊评判模型具有实用性,其评估结果可为干扰措施的选择提供参考。In order to evaluate jamming effectiveness of radar seeker, according to the functioncharacteristics and principle of radar seeker, using fuzzy mathematics theory, this paper builds theevaluation index system of the radar seeker and two -stage fuzzy combined evaluation model.Membership function is established with normal distribution, and the weight of the index system is setup with AHP with index scale which improves the concordance index of judgment matrix and realizesquantized evaluation of radar seeker. Finally, noise jamming is chosen as an example to verity themodel, the example shows the effectiveness of the model and the evaluation results can providesreference of choosing jamming measures.
