摘　　要：针对DS/FH(Direct Sequence/Frequency Hopping,直扩/跳频)混合扩频测控系统抗干扰问题,提出一种效能评价方法。基于任务需求,构建系统抗干扰效能评估指标体系;将三角模糊数、指数标度和层次分析法相结合,提出一种改进的TFN-AHP(Triangular Fuzzy Number-Analytic Hierarchy Process,三角模糊数-层次分析法),提高了较小指标的区分度,剔除了极端数据,最大限度发挥专家的经验知识,实现了指标赋权的客观程度,最后通过AHP对不同设备系统关于指标体系判断矩阵的确定、一致性检验和层次总排序,实现了系统抗干扰效能的评价和选择。分析结果表明,该评价方法能够实现不同设备的抗干扰效能评估,有助于用户对设备的选择。A new effectiveness evaluation is provided for the anti-jamming performance of Direct Sequence/Frequency Hopping （DS/FH） hybrid spread spectrum Tracking, Telemetry and Command （TT＆C ） systems. An anti-jam-ming effectiveness evaluation index system and standardized equation are built, in view of task demand. Through in-tegrating Triangular Fuzzy Number （TFN）, index scale and Analytic Hierarchy Process （AHP）, an improved TFN-AHP is proposed and it improves distinguishing of less index and eliminates extreme data and gets expert knowledge at the most extent. Finally？ system evaluation and optimization is achieved through determination of judgment matrix, consistency test and hierarchical sorting from index system of different equipment system based on AHP. Analysis results show that the evaluation method can achieve anti-jamming effectiveness evaluation of dif- ferent equipment and provide assistance to selection of equipment.
