PURPOSE:To enable to display the non-priority radar video signal simultaneously when the trigger of priority radar video signal and radar trigger of non-priority radar video signal are not in agreement, by storing non-priority radar video signal with the memory circuit. CONSTITUTION:The memory circuits 14-16 store the radar video signal. Further, the display trigger signal is formed from the radar trigger inputted from the input terminals 21 and 22 at the control circuit to the dispaly circuit. Further, the control circuit 31 makes the memory and readout instruction to the memory circuits 14-16, the output of the memory circuits 14-16 is added at the addition circuit 17 to output it to the display circuit. The display circuit 18 uses the trigger signal for display from the control circuit 31 and displays the radar video signal from the input terminal 19 and the output of the addition circuit 17. Thus, even if there is priority and non-priority to the radar trigger, the radar video can perform all the displays. |
