地面作战目标威胁评估多属性指标处理方法

评估指标的量化处理是目标威胁评估(Threat assessment,TA)算法应用的基础.本文针对地面作战目标威胁评估指标类型多样和难以量化的问题,系统地提出了一种多属性威胁指标的量化方法,并将指标量化结果转化为统一的直觉模糊集(Intuitionistic fuzzy set,IFS)表示形式.研究了地面作战目标威...

Multi-attribute Index Processing Method of Target Threat Assessment in Ground Combat

Quantitative processing of evaluation indexes is the application basis of target threat assessment(TA)algorithm.Aiming at the problems that the TA indexes of ground combat targets are various and difficult to quantify,this paper proposes a quantization method of multi-attribute threat indexes systematically,and transforms the quantization results of indexes into a unified intuitionistic fuzzy set(IFS)representation.TA indexes such as target distance,velocity,attack angle,type,visual condition and combat environment are studied.Fuzzy evaluation language,interval number,real number and triangular fuzzy number are used to quantify the indexes in TA.The uncertain information of the indexes is retained with the maximum extent and the complexity of practical applications is reduced.The transformation principle and method that threat indexes in different forms transform into intuitionistic fuzzy number are put forward,and the mathematical proof of theoretical feasibility is given.An example of multi-attribute indexes processing for TA of ground combat targets is given to verify the rationality of the proposed method in quantifying multi-attribute indexes and transforming them into IFS.It shows that the proposed method can provide scientific evaluation data for target TA.
