摘　　要：GNSS(Global Navigation Satellite System)欺骗干扰装备,是“导航战”重要组成,对其效能的有效评估决定了目标任务的成功.但目前存在影响因素的模糊性和不确定性大、因素间影响关系的传递性弱、评估方法适用性差、评估效率低等难点问题.针对这些问题,本文提出一种基于灰色关联分析和模糊综合评判的评估方法.在指标体系搭建完成的基础上,利用层次分析法确定指标权重,并通过纵向计算灰色关联度,得到最优方案;再通过模糊综合评判,得到最优方案的评估结果;最后通过横向计算灰色关联度,来选取与评估结果关联度高的指标.实验证明,本文提出的方法解决了评估存在的难点问题,达到有效评估的目的.GNSS(Global Navigation Satellite System)spoofing equipment is the important components of“Navigation war”.The valid evaluation of its effectiveness determines the success of the target task.However,there are still many difficult issues,such as the great ambiguity and uncertainty of influencing factors,the weak transitivity of influencing relations between factors,the poor applicability of assessment methods and the low evaluation efficiency.To deal with these problems,an evaluation method based on grey relational analysis and fuzzy comprehensive assessment is proposed.Firstly,the optimal scheme is obtained by calculating grey relational degree longitudinally.Secondly,the evaluation results of the optimal scheme are obtained by using fuzzy comprehensive assessment.Finally,the indexes highly correlated with the evaluation results are selected based on calculating gray relational degree horizontally.The test results show that these difficult problems are solved by the method proposed in this paper.
