摘　　要：雷达天线是CINRAD/SA雷达的重要组成部分之一,由于控制过程复杂,且长期处于运行状态,该部分的故障在雷达分系统中一直较多。以新一代天气雷达控制序列超时故障为例,深入剖析了数据采集单元(DAU)与雷达数据采集状态控制处理器(RDASC Processor)之间的状态与控制信息,并总结了关键硬件部分的典型故障排除方法,从而为雷达天线的故障维护、维修和技术支持积累经验,达到迅速排除故障的目的。Radar antenna is an important part of CINRAD/SA. For the complexity of its control process and the long running time, the failure rate of antennas is usually higher than the other parts of the radar subsystems. Taking a control sequences-timeout failure of CINRAD/SA for an example, an analysis is made of the state and control information between the data acquisition unit （DAU） and the radar data acquisition processor （RDASC Processor） in depth, and the key-hardware troubleshooting methods are summarized, for the purpose of the radar antenna maintenance, repair and technical support, so as to accumulate experiences for rapid troubleshooting.
