Abstract
PURPOSE: To enable long-distance transmission over several kM by dividing a device to a coordinate converting part and frame memory part in the part where the data transmission rate is lowest and connecting these parts by a digital information transmission path.
CONSTITUTION: The radar video signal inputted from a radar signal receiver 1 to the coordinate converting part 13 is sent via an A/D converter 4 to a sweep buffer 5. The angle information inputted from an antenna 2 is sent to a coordinate converter 6. The coordinate data outputted from the converter 6 and the digital video signal D read out of the buffer 5 are converted from the parallel data to the serial data and are further subjected to code mark inversion coding. The coded data are transmitted to an optical fiber cable 16. The signal D and coordinate data sent to a frame memory 15 are then converted 14 to parallel data which are stored 7. The signal D stored in the frame memory 7 is converted by D/A conversion 8 to the radar video signal of a TV system which is then sent to a display device 3 and is displayed at a high refresh rate under the control of a display control part 9.
