Abstract:

This patent discloses an underwater acoustic reflector for sonar applications having a title or other geometric form of fibermetal enclosed in a neoprene waterproof envelope and having surface area free of sharp projections that might puncture the envelope when subjected to elevated hydrostatic pressure and which is supported in the vicinity of sonar equipment to reflect away unwanted noise, to modify the acoustic field pattern, or to adjust hydrophone performance by operating as a baffle in the near field.
