The technical project of long-distance and three remote control via optical cable of the 714CD Doppler Weather Radar at Zhengzhou and long-distance wireless and real-time data transmission, synchronous processing and display system was presented. The function of every circuit block and the key technique which was solved were described in detail. The technical project gave us a kind of advanced technical method for the single Dopper Weather Radar information (including raw data and image data) which could be shared at real time by several users at the same time.
