The significance of designing a new realtime meteorological radar monitor system is discussed, and the design of the newtype realtime monitoring system of meteorological radar based on the wideband network technology is introduced. The structure mode and functions of this new system are described, and the feasibility of this design based on the wideband communication system is studied by discussing the TCP/IP and calculating the information quantity of meteorological radar data and the occupied bandwidth. The characteristics of the structure and storage of the realtime monitoring information from CINRAD/SA meteorological radar are analyzed, and the monitoring, receiving, sending, and storing methods of meteorological radar information are introduced. The emphasis is put on the programming of software for information transmitting and storing. According to two basic protocols of the TCP/IP (TCP & UDP) and ADO database programming technology, the longdistance control of the operation of the meteorological radar can be realized in real time based on the existing wideband technology.
