基于直觉模糊区间粗糙集的辐射源威胁等级判定

摘要

In the course of radiator threatening level evaluation, it is difficult to describe precisely threatening of the radiator because there are some intuitionism and fuzzy characteristics in the course of e-lectromagnetic reconnaissance. The intuitionism fuzzy theory and rough sets theory are applied to the realm of radiator threatening evaluation. Taking the intuitionistic index into full account, the intuitionistic fuzzy interzone rough sets is built, whose boundary is lower approximation membership, upper approximation membership + intuitionistic index, and then the decision-making model of intuionistic fuzzy inter-zone rough sets is established. The radiator threatening evaluation index is presented, on the basis of which an example is carried out, and the result shows that this method is feasible and available.%在辐射源等级判断中,由于侦察设备对辐射源各参数的侦测存在很大的直觉性和模糊性,对准确刻画辐射源的威胁带来了不便.通过把直觉模糊和粗糙集的理论引入到辐射源威胁等级判断中,充分考虑直觉指数对隶属度的支持度,构造了下近似为隶属度、上近似为隶属度+直觉指数的直觉模糊区间粗糙集,在此基础上构建了直觉模糊区间粗糙集的决策模型；给出了辐射源威胁的因素集,在此基础上进行了实例验证,结果表明该方法可行有效.
