The overview of the modernisation of weather radar service technology in China over the past 60 years

Weather radar is one of the most important tools for monitoring and early warning of severe convection and typhoons. It also is one of the most effective means for detecting precipitation weather systems and estimating rainfall. Since the No.843-radar was first used for typhoon monitoring in 1964, China''s weather radar has made remarkable progress in technology and operational capabilities. With the new millennium, weather radar has significantly improved the operational meteorological system, as well as the technical capabilities and research investment. The modernization of weather radar technology and public service capabilities has been greatly enhanced. Now China has built the world''s largest weather radar network, with 252 S- and C-band radars comprising the CINRAD network, plus 298 X-band radars for regional observation. And the network is based almost entirely on proprietary core technologies, helping to improve operational efficiency across all technical areas. In this paper，the history of China''s weather radar development over the past six decades has been systematically reviewed, especially the milestones in the evolution of operational and technical systems. The paper also aims to provide historical references for the further development of China''s weather radar, and insight for achieving precision monitoring in future.
