摘　　要：在TWP3风廓线雷达各种故障中,发射机故障率高居榜首。基于TWP3风廓线雷达发射机工作原理和关键点信号特性,结合故障统计数据,将发射机常见故障归纳为6类典型故障。通过分析典型故障,研究出一套故障诊断流程,并结合3个典型案例进行剖析。结果表明:发射机典型故障诊断流程可以快速、准确诊断发射机故障,具有思路清晰、操作规范、基层雷达站技术人员容易掌握的特点,可有效缩短发射机故障修复时间,提高TWP3风廓线雷达技术保障水平。Among all kinds of faults of TWP3 wind profiler radar,the failure rate of transm itters is the highest.At present,there is still a lack of a transm itter fault diagnosis method suitable for the technical personnel of radar stations.Based on the working principle and key point signal characteristics of TW P3 wind profile radar transm itters,combined with fault statistics,the common faults of the transm itters are classified into six types of typical faults.By analyzing these typical faults,a method for diagnosing typical faults by means of the flow chart is developed,and three typical cases are analyzed.The results show that this method can diagnose the transm itter faults quickly and accurately.It has the characteristics of clear thinking,standardized operation and being easy to grasp by the technical personnel of radar stations.It can effectively shorten the repair time of transmitter faults and improve the technical support level of TWP3 wind profile radar.
