PURPOSE:To display plural radar video echoes at the same time by displaying one radar video in real time and quantizing and storing other radar videos, and displaying the quantized videos when the real-time video is displayed. CONSTITUTION:A video storage circuit 4 quantizes and stores the video-number sweep component of a radar 2 and this is outputted under the control of a video switching circuit 5. The video switching circuit 5 inputs and outputs a real-time video from a radar 1 to a display device 6, and the time when the real-time video is not displayed is utilized to input a quantized video from the video storage circuit 4 and outputs it to the display device 6. The display device 6 displays video echoes of two radars which are sent from the video switching circuit 5 on a time-division basis. |
