するカラースキヤニングソーナー。 The spiral scan signal obtained by scanning the receiving beam all around 360° is converted into a raster scan signal, and the received image can be drawn on a circular display area of a fixed area formed on the display screen of a color display device. In addition, in a color scanning sonar equipped with a video transmission control section that transmits a detected image to the outside; a transmission pixel forming means for forming a plurality of transmission pixels defined by a central circle and a plurality of azimuth lines orthogonal to each concentric circle and spaced by the directivity width of the received beam; determination means for determining the number of scans of the received beam for the determination; transmission image data determination means for determining transmission image data from the spiral scan signal based on the determination result of the determination means; A transmission buffer that is sequentially stored according to the scanning order of the receiving beam; and a readout control means that sequentially reads the transmission image data from the transmission buffer according to the storage order. Color scanning sonar.
