Definitions

  • the invention relates to an electroacoustic underwater antenna, in particular on the outer skin of underwater vehicles attachable side antennas, the genus defined in the preamble of claim 1.
  • a well-known side antenna for submarines is known from EP 0 214 525 B1 discloses all the features of the preamble of claim 1, is formed by a so-called.
  • Hydrofonstreamer which is held over its longitudinal extension of spaced from each other on the submarine shell holding members at a distance from the submarine shell.
  • the hydrophone streamer has a flexible hose which is supported by fittings at certain intervals.
  • the arranged in the hose at defined intervals hydrophones are each arranged between two on the hose jacket supporting fittings.
  • the cylindrically shaped hydrophones sit in a clamped on traction cables bracket.
  • This holder is composed of two resilient plastic halves, the traction cables half each comprehensive end portions are held together by spring clips.
  • the middle part of the holder encloses a cylindrical cavity in which the hydrophone is resiliently held.
  • the hose jacket is filled with a liquid, preferably oil, which ensures good acoustic transmission properties between the hydrophones and the hose jacket.
  • a known, designed as a so-called towed antenna underwater antenna ( DE 198 12 356 C1 ) has a filled with a filler hose in which a plurality of hydrophones are lined up at a distance one behind the other and held by support on the tubular casing approximately centrally in the hose.
  • a filler hose in which a plurality of hydrophones are lined up at a distance one behind the other and held by support on the tubular casing approximately centrally in the hose.
  • spaced pieces of metal foam are provided in the longitudinal direction of the tube, in which the hydrophones are used centrally.
  • the fittings are set on a pull rope pulling through the hose.
  • the hose is filled with oil.
  • a filler gel which surrounds the hydrophones uniformly on all sides and so fixed in the tube substantially centrally.
  • the filler is a two-component silicone rubber, the two components of which are highly fluid and highly fluid and harden at room temperature to a gel-like vulcanizate.
  • Cylinder base underwater antenna ( EP 0 654 953 B1 ) is a plurality, for example ninety-six, of rod-shaped transducer assemblies, so-called. Staves, attached to the outer jacket of a hollow cylinder made of glass fiber reinforced plastic side by side. Each stave has several, for example three, at the same distance superimposed hydrophones, which are designed as small ball ceramics. In sound incident direction behind the hydrophones, a reflector is arranged. Hydros and reflectors are embedded in an acoustically transparent hard cast of polyurethane.
  • connection lines of all hydrophones are led to a common plug, which is in one at one end of the Hartumgusses molded-in blind hole protrudes.
  • Such an underwater antenna has a directional characteristic with a sufficiently narrow main lobe in the vertical direction with suitable signal processing of the hydrophone output signals due to the plurality of vertically superimposed hydrophones.
  • the invention has for its object to provide an underwater antenna of the type mentioned, which in addition to a horizontally pivotable narrow main lobe of the receiving characteristic also has a sufficiently large bundling in the vertical direction and a good reception sensitivity in the low-frequency range and also manufacturing technology is easy to manufacture and easy to assemble ,
  • the underwater electroacoustic antenna according to the invention combines the acoustic advantages of a hydrophone streamer with respect to its low-frequency reception sensitivity and the advantages of a cylinder base or planar antenna with respect to good confinement of the vertical reception range.
  • the rigid support plate serves as a reflector and gives the underwater antenna a good forward / reverse ratio.
  • the production of the plastic body is very easy to manufacture, as well as the insertion of the hydrophones in the cavities.
  • a plurality of plastic bodies fitted with a thermoplastic are arranged next to and / or behind one another.
  • montagetechnisch simple juxtaposition of the individual plate-like plastic bodies so-called.
  • Panels containing arranged in row and columns hydrophones can be realized with low manufacturing cost an area antenna with any dimensions.
  • the plastic body forming a panel is made as a rigid encapsulation enclosing the rigid plate in which cavities are formed in front of the plate surface at a distance from these mutually parallel channels.
  • An equal number of hydrophones are placed in a closed, oil-filled tube and a tube is drawn into each channel.
  • the hose is preferably made of polyethylene.
  • an equal number of hydrophones are each used directly in the channels formed in the Hartumguss, supported on the channel walls by means of conventional fittings and fixed axially immovable.
  • the channels are preferably filled with oil and sealed.
  • the electroacoustic underwater antenna is a surface antenna, which is preferably used as attached to the outer skin of a submersible side antenna. It is composed of a plurality of panel-like antenna elements 10, which are arranged one behind the other and / or next to each other and individually secured to the outer skin of the underwater vehicle.
  • Each antenna element 10 has an acoustically transparent, plate-like plastic body 11, on the one hand a rigid plate 12 and on the other hand in the direction of sound incidence before the plate 12 arranged hydrophones 13 contained in the plastic body 11, at a parallel distance from each other and the plate 12th extending cavities 14 are arranged.
  • each antenna element 10 forms a panel with a hydrophone arrangement in which the hydrophones 13 are positioned in rows and columns.
  • the plastic body 11 is made as a rigid encasing surrounding the rigid plate 12, in which channels 15 are formed in front of the plate surface at a distance from these parallel to one another to form the cavities 14 ( Fig. 2 ).
  • the hard encapsulation consists of a casting processable, substantially viscoelastic elastomer, preferably of polyurethane.
  • An equal number of hydrophones 13, in the illustrated example six hydrophones 13, are inserted in a closed, oil-filled tube 16 and fixed at radial distance from the tubular casing 161 axially immovably in the tube 16, wherein the distance of the successive hydrophones 13 is constant ( Fig. 3 ).
  • the designed as a small ball ceramics hydrophones 13 are for this purpose received in each case a plastic holder 17, which is supported on the tubular casing 161 and fixed axially immovable.
  • the oil filling 18 is in Fig. 3 indicated by punctuation.
  • the introduction of the plastic holder 17 with hydrophones 13 can be done, for example, that the plastic holder 17 are fixed in a very coarse-mesh network and the net is floated with the fixed hydrophones 13 in the tube 16.
  • the hydrophones 13 can be used by means of their plastic holder 17 directly into the channels 15 at a defined distance from each other.
  • the so equipped with hydrophones 13 channels 15 are filled with oil and closed at the end.
