Abstract

Traditional underwater target noise signal modulation spectrum analysis methods is based on the second-order statistics characteristics in the Gaussian noise environment, but in most cases underwater acoustic signals, such as ship-radiated noise and marine environment noise, have pulse characteristic that subjecting to stable distribution typically. Under this condition the second-order statistics of the modulation spectrum analysis algorithm performance not only be declined, but also can not be stable convergence any more. Aiming at this problem, the fractional lower order statistics of the target signal modulation spectrum analysis method was proposed, and technique for choosing order of fractional was debated. Simulation and experimental data results show that proposed method is robust.
