New GenerationWeather Radar has become a chief means of monitoring the severe convective weather events occurred in Lanzhou and its surrounding areas. This paper analyzed data error sources in radar front - end and back - end p rocessing. Itwas found that clutter, radar antenna gain, monitoring distance and data interpolation, coordinate conversion, remote transmission to several ter2 minals are mainly error sources in radar front - end and back - end p rocessing, respectively.
