摘　　要：雷达系统状态评价问题涉及因素多,且各因素大都具有模糊不确定性。在确立评价指标体系的基础上,文中提出了基于层次分析法和模糊评判理论的雷达系统状态评价方法。针对多因素判断矩阵难以满足一致性难题,采用传递矩阵实现了多组决策数据的一致性处理,从而获得指标的综合权值。针对因素指标类型的差异性,提出指标劣化程度的度量方法,并利用所构造的三角隶属函数对指标状态进行了模糊划分,最大综合隶属度即为对应雷达系统所处状态。最后,通过实例验证了该方法的合理性和有效性。Radar system state evaluation involves many factors, and most of the factors have fuzzy uncertainty. On the basis of es-tablishing evaluation index system, an evaluation method of radar system state based on analytic hierarchy process （AHP） and fuzzy is proposed in this paper. For the problem that multi-factor comParison matrix is difficult to meet consistency is achieved by transfer matrix theory, then the comprehensive weight of each index is obtained. Aiming at difference of various indexes, methods of measuring indexes are put forward. And the indexes＇states are divided by triangular membership functions. The maximum membership corresponds to the state of radar system. Finally, an exampte shows that the method is reasonable and effective.
