Acoustic Communication With Small UUVs Using a Hull-Mounted Conformal Array
NAVAL UNDERSEA WARFARE CENTER DIV NEWPORT RI
Pagination or Media Count:
A new conformal array designed to enhance acoustic communication on small unmanned underwater vehicles UUVs is presented. The array is intended to improve the reliability and rate of acoustic communication to UUVs under conditions of multipath, multiuser interference, broadband or narrowband jamming and low signal-to-noise ratio. The array elements are constructed from a piezocomposite material that can be injection molded to nearly any shape, including into curves that match the hull radius of the vehicle. The array is encapsulated into a low-profile assembly 0.02 m thick and bonded directly to the hull of a REMUS vehicle. The frequency response and beampatterns rectly to the pressure vessel.
