Review on passive sonar target recognition
DING Yu-wei(Shanghai Acoustic Laboratory, Chinese Academy of Sciences, Shanghai 200032, China)
Automatic recognition of underwater targets is one of the key techniques in modern passive sonar systems. The techniques of feature extraction,feature selection and design of classifier for passive sonar target recognition are reviewed. The feature extraction techniques such as LOFAR, DEMON, wavelet transform and so on are discussed. The importance of feature fusion and the advantages and disadvantages of classifiers such as expert systems, neutral networks are analyzed. The past, present and future of this field are also briefly discussed.
