Abstract:

A passive acoustic detector including a line hydrophone and apparatus coupled thereto operable to utilize the energy sensed by the elements of the hydrophone during passive listening to effect scanning in depression-elevation by delaying for directivity and then combining acoustic energies sensed by the hydrophone elements and recording the combined energies on a x-y strip recorder for enhanced signal-to-noise ratio.
