Abstract
A sonar includes a first part and a second part linked by an electric carrier cable configured to mechanically support the second part and allow the two parts of the sonar to exchange signals comprising: a unidirectional signal, called electrical power supply signal, unidirectional signals, called signals to be emitted, transmitted by the first part to the second part for them to be transmitted in the form of acoustic waves, and a bidirectional signal conveying communication data, the sonar wherein the first part comprises signal combination means configured for the signals to be transmitted simultaneously over the electric carrier cable, and in that the second part comprises separation means allowing the recovery of each of the signals transmitted over the electric carrier cable.
Claims11
A sonar comprising a first part and a second part linked by an electric carrier cable configured to mechanically support the second part and allow the two parts of the sonar to exchange signals, comprising:
- a unidirectional signal, being an electrical power supply signal, by which the first part transmits an electrical power supply to the second part,
- analog unidirectional signals, being signals to be emitted, transmitted by the first part to the second part to be emitted in the form of acoustic waves, and
- a bidirectional signal conveying communication data exchanged between the two parts,
- wherein the first part comprises signal combination means configured so that the electrical power supply signal, the signals to be emitted and the signal conveying communication data are transmitted simultaneously and in different frequency bands over the electric carrier cable, and
- the second part comprises separation means allowing recovery of each of the signals transmitted over the electric carrier cable, one or more emission acoustic transducers, and tuning/matching means of the emission acoustic transducer or transducers.
