Abstract
The response of a towed array to noise from its tow-ship is simulated in a bottom-limited ocean environment. This study requires the near-field solution of a shallow radiating source. The relation between the Greens function of the wave equation for a given environment and the output of the towed array beamformer is derived. Numerical results suggest that the beamformed output is useful as a diagnostic tool to establish the acoustic properties of the bottom.
