摘要
针对大型相控阵雷达系统安全性因素多、评价困难的特点,分析并建立了大型相控阵雷达系统安全评价指标体系。提出了一种基于改进模糊层次分析法、熵权法和拉格朗日算法确定综合权重的方法,并建立了雷达系统安全性模糊综合评价模型。以某型大型相控阵雷达系统的安全性评价为例,运用所提方法确定该雷达系统的安全性指标综合权重,并进行安全性综合评价。将该方法与传统AHP评价法进行对比分析,验证了该方法的科学性和合理性。
In view of the LPAR(large phased array radar)system has too much safety factors and it is difficult to evaluate.Firstly,the LPAR safety evaluation index system based on the radar characteristic was analyzed and established.Secondly,a method to determine the comprehensive weight based on the improved FAHP(fuzzy analytic hierarchy process),entropy weigh and Lagrange algorithm was put forward,and the safety fuzzy comprehensive evaluation model was established.Thirdly,taking safety evaluation of the certain LPAR system as an example,the safety comprehensive weight of the LPAR system was determined by the proposed method,the safety evaluation was carried out by the established model.Finally,this method is compared with the traditional AHP method,and the feasibility and rationality of the method are verified.
