  • Underwater detection apparatus and underwater detection method
    Patent number: 11668822
    Abstract: An underwater detection apparatus is provided which includes a transmission transducer, a reception transducer, and a motor. The transmission transducer transmits a transmission wave within a given fan-shaped transmission space, the fan-shaped transmission space having a first transmission width in a given first plane and a second transmission width in a second plane perpendicular to the first plane. The reception transducer receives, as a reception wave, a reflection wave of the transmission wave within a given fan-shaped reception space, the fan-shaped reception space having a first reception width in the first plane and a second reception width in the second plane, the second reception width being wider than the second transmission width, and in the second plane, the fan-shaped transmission space being within the fan-shaped reception space. The motor rotates the fan-shaped transmission space and the fan-shaped reception space.

  • UNDERWATER DETECTION APPARATUS AND UNDERWATER DETECTION METHOD
    Publication number: 20210096245
    Abstract: An underwater detection apparatus, which includes a transmission transducer, a reception transducer, and a motor, is provided. The transmission transducer is configured to transmit a transmission wave within a given transmission fan-shaped space, the transmission fan-shaped space having a first transmission width in a given first plane and a second transmission width in a second plane perpendicular to the first plane. The reception transducer is configured to receive a reflection wave of the transmission wave within a given reception fan-shaped space, the reception fan-shaped space having a first reception width in the first plane and a second reception width in the second plane, the second reception width being narrower than the second transmission width, and in the second plane, one of a pair of edges of the transmission fan-shaped space being within the reception fan-shaped space. The motor is configured to rotate the transmission and the reception fan-shaped spaces.
