Abstract:

The validity of air target recognition is very important for air defense combat. Concerned with the characteristics of air target recognition, intuitionistic fuzzy clustering is presented. Some valid measures of similarity and dissimilarity are griven; and with target characteristics, intuitionistic fuzzy similarity and dissimilarity are obtained. Serveral existing construction methods of the intuitionistic fuzzy similarity matrix are analyzed, a new construction method of intuitionistic fuzzy similarity matrix is put forward. An approach to transforming the intuitionistic fuzzy similarity matrices into the intuitionistic fuzzy equivalence matrices is given. Moreover, the (α,β) cutting matrix of intuitionistic fuzzy equivalence matrix is given, and a method of clustering intuitionistic fuzzy sets is proposed. Finally, based on this method, the clustering analyses of the air targets with specific characteristics are carried out. The result of experiment shows that this method is feasible and effective.
