Identification And Classification Of Information Fusion-based Target

In this paper, many features of ship's radiated noise are extracted by the means of techniques in modern signal process, and the theory of information fusion is used for calculating basic belief assignment and identification and classification of targets. The aim is to fuse multiple features and identify ships more accuracy. In the paper, there are:Analysis of acoustic characteristics of ship's radiated noise both in time and frequency domain, especially of its tonal noise. Extraction features of Ship's radiated noise from its bispectrum , one and a half spectrum , two and a half spectrum, Singular value of STFT, wavelet transform, and so on. Studing theory and algorithm of information fusion and useing Dempster-Shafer' evidence inference theory to classify three types ships and gained satisfied result.
