摘　　要：文章根据天气雷达天线运行控制的特点,提出了一种基于天气雷达运行日志的天线状态在线检测方法,定义了扫描层方位平均速度、方位零点误差和俯仰平均误差等检测参数,以及基于天线方位角度和俯仰角度采样数据的参数值计算和异常判别方法,并对检测方法应用中需要注意的问题进行了说明。在武汉CINRAD/SA天气雷达的试验应用检验表明,该检测方法可在天气雷达体扫运行状况下,实时、准确地监测天线运行状态及异常甄别,且易于实现。According to the characteristics of weather radar antenna operation control,an online detection method of antenna status based on weather radar operation log is proposed,which defines the detection parameters such as scanning layer azimuth average velocity,azimuth zero error,and elevation average error.Based on antenna azimuth angle and pitch angle sampling data,the parameter value calculation and abnormal discrimination method are defined.At the same time,the problems that need attention in the application of the detection method are explained.The test application of Wuhan CINRAD/SA weather radar shows that the proposed detection method can monitor the antenna operating status and abnormality in real time and accurately under the operating conditions of weather radar volume coverage pattern scanning,and is easy to implement.
