Separation of moving ship striation patterns using physics-based filtering

  title={Separation of moving ship striation patterns using physics-based filtering},
  author={Y. L. Gall and J. Bonnel},
When a ship is moving toward an acoustic receiver in an oceanic waveguide, the time-frequency representation of the recorded signal exhibits a striation pattern that can be useful in numerous applications such as ship localization or geoacoustic inversion. If there are many ships, the striation patterns add up and they must be separated if one wants to study them separately. In this paper, a physics-based filtering scheme for passive underwater acoustics has been developed. The algorithm allows… Expand
