Considering the proposed aerial targets type recognition is not fully ideal,a new method of aerial targets type recognition based on vague sets is presented.Weight calculation of targets type characteristic parameter is offered,which can avoid subjective deviation resulted from expert evaluation method availably.Based on aerial targets type recognition standard,a weighted Vague distance function and mathematical model of aerial targets type recognition are established by multiple-attribute fuzzy decision theories.Finally,via an example,the result of the method is proved to be correct.The proposed method is valuable for the commander’s decision making.
