摘要：
Vessel radiated noise is somewhat similar to fractional Brownian motion. Accordingly, the standard deviations of differential sequences and fractal dimensions are extracted as features that reflect time-domain information other than traditional features. Six types of vessel can be classified correctly, which indicates that fractal features are useful for vessel noise recognition.
