【Abstract】 This paper discusses feature fusion technique in underwater target recognition and proposes the method dealing with the problem encountered.Then,fuzzy fusion classifier (FFC) was designed based on this concept.FFC does not make any assumption about samples’ distribution in pattern space,but emphasizes mutual restraints among classes and the independent role of each pattern and synthesizes those role by operation like combination in fuzzy logic.In practice,FFC can efficiently improve classification performance of recognition system by synthesizing features from multisensors.更多还原
