PURPOSE:To obtain three-dimensional display which displays detection signals of different depth in different colors, one over another, over one screen of a CRT, by providing a changeover switch, an address conversion memory, and a display memory for every interval of depth. CONSTITUTION:Transmitted and received waves of ultrasonic wave pulses and return reflected waves from every direction are received by respective oscillators 3, and information on detection at a three-dimensional angle based upon one- time transmission is stored in a buffer memory 10. To display the stored three- dimensional detection information in various two-dimensional display modes, information is transferred from specific addresses of the buffer memory 10 to a display memory 22. A changeover switch 25 is connected to the side of a counter 23 or 24 to transfer storage information on an address to an address conversion memory 21 to a corresponding address of the display memory 22. While a changeover switch 26 is placed at a readout side, stored signals read out of the display memory 22 are sent to a color converting circuit 33, and respective color signals are led to the red, green, and blue terminals of a CRT27 to be displayed. |
