Bispectrum Feature Analysis of Ship-radiated Noise
This paper analyzed spectrum features of ship-radiate noises of three types of ships, using indirect algorithm of nonparameric bispectrum estimation. The results show that different ship noise has different bispectral constructions. From diagonal slice of amplitude spectrum, 3 features: the number of line spectrum, the frequency scope of maximum line spectrum, the position of first line spectrum were extracted and analyzed.
