An Extended Algorithm of Similarity Measures and Its Application to Radar Target Recognition Based on Intuitionistic Fuzzy Sets

摘要

The main purpose of this study was to extend an algorithm proposed by Liang and Shi in 2003 for the measurement of similarity in pattern-recognition problems. The third measure of similarity in their algorithm fails to satisfy the necessary criteria, thereby invalidating their claims. In this study we developed two new approaches that satisfy the four axioms associated with the measurement of similarity. We then implemented these measures in a new algorithm and used numerical examples to examine the problem encountered by Liang and Shi. Finally, we evaluated the applicability of the proposed algorithm in a problem involving radar target recognition. Our findings provide a solid foundation for the development of a logical framework with which to select an appropriate measure of similarity for pattern-recognition problems.
