  • Method of measuring the acoustic backscatter property of the floor of bodies of water
    Patent number: 5485432
    Abstract: A method is provided for measuring the acoustic backscatter property of the floor of a body of water in which an acoustic multibeam echosounder employed on a ship is used to measure the sonic backscattered from a narrow transmission target strip on the sea floor that extends essentially vertically beneath the center of the transmitting antenna, transversely to the travel direction of the ship and which is successively exposed to sonic pulses by the transmitting apparatus. The measured backscatter is converted into sonic backscatter values allocated to receiving strips (115) of the multibeam echosounder. Calibration curves are constructed for all floor elements along the course line of the ship by echosounder measurements during a calibrating operation following a 90.degree. pivot of the echosounder around the vertical axis of the ship.
