  • Patent number: 7483336
    Abstract: One or more embodiments of the present invention are aimed at a device for ships, in particular for multihull ships and high-speed multihull ships making it possible to avoid obstacles, in particular obstacles submerged at low depth. In at least one embodiment, the device according to the invention comprising at least: two transmitters of acoustic waves spaced apart from one another and transmitting waves of distinct frequencies or of different waveforms, an acoustic receiver, whose reception band is suitable for the emission frequencies of the transmitters, means of processing of the received signals, these means performing, through the echoes received, a measurement of the difference of the propagation times and a measurement of the differential Doppler frequency of the waves transmitted by each of the transmitters; these processing means thus determining from these measurements the position of and object having returned an echo.
