PURPOSE:To display video signals of a plurality of radars on the same display apparatus, by installing a plurality of video memory circuits introducing and storing video by connecting with radars and a video switching circuit which issues by switching according hour and minute each video by connecting it with the video memory circuit. CONSTITUTION:Outputs of radars 1 and 2 are transmitted to a display apparatus 3. Two video memory circuits 4 of the apparatus 3 store by quantization of the sweep portion of video number of radars 1 and 2 connected respectively and issued respectively by controlling from a video switching circuit 5. The circuit 5 receives consecutively the quantized videos stored from the two circuits 2 and both videos are issued by switching according to hour and minute and a display apparatus 6 overlaps videos of the radars 1, 2 transmitted from the circuit 5 for display. Thus, a single operator observes a plurality of videos of the radars simultaneously and a display apparatus available for grasping of condition can be constructed. |
