基于ANP和优化隶属度函数的雷达质量评估研究

A Study on Radar Quality Evaluation Based on ANP and Optimal Membership Function

为检验雷达系统质量状况,依据其应用需求和功能特性,构建了雷达质量状况评价的指标体系。针对各层级指标因素间可能存在一定关联性的情况,文中采用网络层次分析法确定指标权重。针对单一隶属度函数可能产生隶属度突变的问题,提出了组合隶属度函数的方法,通过计算各指标在不同隶属函数下的评价信息,而后对多种隶属函数的评价信息进行优化组合,使得评估结果具有更高的可信性。运用模糊综合评判的方法,对某雷达系统质量进行了实例评价分析,结果表明该方法简易可行,能够较为准确地评估雷达装备的质量状况。

In order to test the quality status of radar system,according to its application requirements and functional characteristics,an index system for evaluating radar quality status is constructed.Aiming at the fact that there may be a certain correlation between the index factors at various levels,this paper adopts the network analysis hierarchy process to determine the index weight.Aiming at the problem that a single membership function may produce sudden changes in membership,a method of combining membership functions is proposed.By calculating the evaluation information of each indicator under different membership functions,the evaluation information of various membership functions is optimized and combined,so that the evaluation can be achieved.The results have higher reliability.The fuzzy comprehensive evaluation method is used to evaluate and analyze the quality of a radar system.The results show that the method is simple and feasible,and can more accurately evaluate the quality of radar equipment.
