<p>PURPOSE:To display the data of a plurality of sensors on the tube surface of a CRT by displaying a plurality of video signals on the tube surface of the CRT in a time sharing manner. CONSTITUTION:When the indication trigger synchronous to a radar transmission pulse is applied to a timing control circuit 1, a sweep gate signal, a brightness gate signal, a range mark gate signal and a video change-over signal are respectively outputted to a sweep generating circuit 3, a brightness gate control circuit 7, a range mark generating circuit 8 and a video change-over circuit 10 by the timing control circuit 1. The antenna azimuth angle signal applied to an azimuth angle control circuit 2 is decomposed on the basis of the vertical and horizontal components to an antenna azimuth angle to be applied to the sweep generating circuit 3. A CRT controlled by deflecting circuits 41, 42 and the brightness gate control circuit 7 and the video signals 1, 2 mixed with the range mark signal in a video amplifying circuit 9 are displayed, for example, on the inside and outside of a tube surface of the CRT in a time sharing manner.</p> |
