    • Abstract
  • A method of blind source separation for ship-radiated noise is proposed based on single observing channel. According to the spatial characteristic of ship-radiated noise in far field,a virtual channel is constructed from the observed channel by time delay and data filtering.It overcomes the limitation of channel numbers.The simulation and experimental results using this method are presented.The results show that under the sea ambient noise the shipradiated noise can be separated by this method with single observing channel,and it is effective for two object ships to be separated.
