Claim 0:
1. An underwater ultrasonic device comprising:
a curvilinear ultrasonic transducer; and
a plurality of straight linear ultrasonic transducers comprising a first straight linear ultrasonic transducer and a second straight linear ultrasonic transducer, the curvilinear ultrasonic transducer, the first straight linear ultrasonic transducer and the second straight linear ultrasonic transducer being plate-shaped, the second straight linear ultrasonic transducer being stacked with the first straight linear ultrasonic transducer at a first flat side surface of the curvilinear ultrasonic transducer, an projection of an intersection between the first straight linear ultrasonic transducer and the second straight linear ultrasonic transducer onto a plane where the first flat side surface of the curvilinear ultrasonic transducer is located being within an area of the first flat side surface of the curvilinear ultrasonic transducer, a first angle being included between the first straight linear ultrasonic transducer and the second straight linear ultrasonic transducer, one of the curvilinear ultrasonic transducer, the first straight linear ultrasonic transducer and the second straight linear ultrasonic transducer being configured to transmit a plurality of ultrasonic signals, another one of the curvilinear ultrasonic transducer, the first straight linear ultrasonic transducer and the second straight linear ultrasonic transducer being configured to receive a plurality of reflected signals of the ultrasonic signals.
