Abstract: Effective feature extraction of Radar Emitter Signals（RES） is an important basis for the recognition of advanced radar emitter signals. To achieve the characteristics evaluation of the advanced radar emitter signal, the evaluation model based on Fuzzy Analytic Hierarchy Process（FAHP） method is proposed. This model is established on the feature evaluation index system of advanced radar emitter signal. It aims at the deficiencies of Analytical Hierarchy Process（AHP） in weight determination, and describes the ambiguity of experts’ judgment through the introduction of triangular fuzzy numbers. The model is applied to RES feature evaluation case analysis, and its calculated results are compared with the results of AHP.

摘要： 提取有效的雷达辐射源信号特征是复杂体制下雷达辐射源信号识别的重要基础。为实现对复杂体制雷达辐射源信号特征的评价，提出了复杂体制雷达辐射源信号特征的模糊层次分析评价模型。该模型在构建复杂体制雷达辐射源信号特征评价指标体系的基础上，针对层次分析法在权重确定方面存在的不足，通过引入三角模糊数来刻画专家评判的模糊性，将该模型应用于雷达辐射源信号特征评价的算例分析，并将计算结果与标准层次分析法的分析计算结果进行了对比，结果表明该模型的计算结果与标准层次分析法的计算结果是一致的，从而证明了该模型的可行性和有效性。
