Architecture of an acoustic system Multistatic

This invention relates to a multistatic sonar system having a particular mode of communication between the emitting base and the receiving bases responsible for the detection of sonar echoes. This system allows in particular to overcome the drawbacks caused by the use of radio communications generally or satellite communications utilisees.Le signal transmitted by the transmitting base includes a notice pulse carrying information relating to the system operation mode according to invention, especially the transmission time, and a pulse properly dite.Ce sonar system is particularly intended for use by underwater diving buildings for detecting and locating surrounding objects or control positioning of an autonomous underwater vehicle.
