中文摘要: 文章提出了一种基于CINRAD/SC新一代天气雷达地物回波强度和速度数据的质量检测方法。通过采集天气雷达按统一的参数进行标定后的晴空标准地物回波强度作为模版，与实时采集的回波强度进行比较和误差分析，以及通过移相来自动检测速度数据理论值和实测值的误差大小，对回波强度数据和速度数据质量进行检测和校正，以此来实现对天气雷达探测精度的提高。
中文关键词: 新一代天气雷达， 地物回波检测，校正
Abstract:A method of quality detection about ground echo intensity and speed of CINRAD/SC new generation Doppler weather radar is proposed in this paper. First, calibrate all the weather radars by same parameters, and collect ground echo intensity data as a template on clear days. Then compare it with real time echo intensity data. Through phase shift, the speed data are automatically tested by the sides of error between measured and theoretical values and the echo intensity and speed data is detected and corrected to achieve high detection precision of weather radar.
