Abstract
Obtaining valid data of accelerating propeller cavitation noise is benifial for finding the relationship between the ship feature and its radiated sound souce. This paper studies the criteria ruling the measurement of accelerating propeller noise signal in cavitation tunnel, and analyzes the signal model of the measured noise. Based on the signal model, the paper studies the fractional Fourier domain analysis method to extract interested cavitation noise from the measured noise.
