  • Bottom-sediment classification device and method
    Patent number: 7760586
    Abstract: A device and method for determining bottom sediment is provided. The method includes transmitting a pulse of a pulse width corresponding to a water-bottom depth, extracting a series of amplitude data of water-bottom echo signals from predetermined signals among the water-bottom echo signals received by the transducer at a predetermined time interval, normalizing the extracted series of amplitude data after TVG-processed, calculating two or more feature quantities based on the normalized series of amplitude data in each of segments of the normalized series of amplitude data, and a value corresponding to the water-bottom depth, and generating bottom-sediment classification information indicating the bottom sediment based on the two or more feature quantities.
    Type: Grant

    Date of Patent: July 20, 2010
    Assignees: The University of Tokyo, Furuno Electric Company Limited
    Inventors: Teruhisa Komatsu, Akira Okunishi, Nicolas Borrallo, Takeharu Yamaguchi
