| 摘 要： | 新一代天气雷达目前已经成为对兰州市及周边地区短时强烈天气进行监测的主要手段之一。为了方便资料的处理和分析,提高观测资料准确度,为预报员和科研人员分析资料提供方便,通过对雷达数据前端生成和后端处理传输2个过程的分析,找出兰州新一代多普勒天气雷达数据误差的来源,并进行分析,发现地物回波、雷达天线增益、测量距离等因素和数据插值、坐标转换、远距离多终端传输等因素分别是前端数据产生过程中和后端数据处理传输过程中数据误差的主要来源。

| Abstract: | New Generation Weather 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 processing.It was found that clutter,radar antenna gain,monitoring distance and data interpolation,coordinate conversion,remote transmission to several terminals are mainly error sources in radar front-end and back-end processing,respectively. |
