| description | An underwater detection apparatus is provided, which may include a transmission transducer, a reception transducer, and processing circuitry. The transmission transducer may transmit a transmission wave in an underwater transmission space. The reception transducer may include a plurality of reception elements, each reception element generating a reception signal based on a reflection wave comprising a reflection of the transmission wave on an underwater target. The processing circuitry may perform beamforming in each of a plurality of reception spaces based on the reception signals, generate a 3D image data of the target based on the beamforming performed in each reception space, and extract a contour of the target detected in at least one of the reception spaces, and generate a contour image data to be displayed along with the 3D image data on a display unit. |
