摘要： The purpose is to provide an underwater detection apparatus and an underwater detection method, capable of both speed-up of an updating cycle of a detection result image and prevention of a reduction in a detection range. An underwater detection apparatus 1 is provided with a transmission transducer 11 configured to transmit a transmission wave within a transmission fan-shaped space T1, the transmission fan-shaped space T1 having a second transmission width Tθ2 in a second plane P2; a reception transducer 13 configured to receive a reflection wave of the transmission wave within a reception fan-shaped space R1, the reception fan-shaped space R1 having a second reception width Rθ2 in the second plane P2, the second reception width Rθ2 being narrower than the second transmission width Tθ2, and in the second plane P2, one of a pair of edges Te1 and Te2 of the transmission fan-shaped space T1 being within the reception fan-shaped space R1; and a motor 16 configured to rotate the transmission fan-shaped space T1 and the reception fan-shaped space R1.

摘要： A signal processor (10, 10a, 10b, 10c, 10d, 10e) for processing target echo signal is provided. The signal processor (10, 10a, 10 , 10c , 10d, 10e) includes a filtering module (20) configured to generate a filtered echo signal by extracting echo signal components within a predetermined frequency band from the target echo signal, a high resolution signal generating unit (16, 16a, 16b) configured to generate a high resolution signal based on the target echo signal, and a synthesizing module (21, 23, 21a, 27) configured to synthesize the filtered echo signal with the high resolution signal. The high resolution signal has higher resolution than the filtered echo signal.

摘要： A detection device capable of detecting a 3D position of a target object in a comparatively short period of time at low cost is provided. An ultrasonic detecting device 1 may include a transmitter 2, a receiver 3, a rotation driving part 4b, an echo signal acquiring module, an image data generating module, and a synthesized image data generating module. The transmitter 2 may transmit a first sequence in which a time interval between a first pulse wave and a second pulse wave being set as a first time interval shorter than a time required for an ultrasonic wave to go and come back underwater in the detection range. The receiver 3 may convert reflection waves of the first pulse wave and the second pulse wave into echo signals. The rotation driving part 4b may rotate the receiver 3. The echo signal acquiring module may acquire, from the echo signals, a first echo signal and a second echo signal. The image data generating module may generate first image data based on the first echo signals and second image data based on the second echo signals. The synthesized image data generating module may generate synthesized image data based on an angular position of the receiver 3 when the first image data is generated, and an angular position of the receiver 3 when the second image data is generated.
