摘　　要：针对一种雷达系统故障诊断的复杂性,设计了故障诊断专家系统。选取载波信号失锁作为雷达系统典型故障,通过建立故障树获取专家系统知识并进行知识表示。专家系统先根据设备中的实时监测点信息缩小诊断范围,而后按照故障树事件重要度,采用串行与并行相结合的推理方式进行故障诊断。专家系统知识来源可靠,推理科学合理,具有一定的实用性和推广性。Aimed at the complexity of the fault diagnosis of a certain type of radar, the fault dagnosis espert system is designed. Choosing carrier wave signal being unlocked as the representative fault of the radar system, the expert system knowledge is acquired by constructing the fault tree and represents it. The confines of diagnosis is reduced by expert system on the basis of the information of real-time surveillance, and then, fault is diagnoses in manner of serial and parallel reasoning according to the importance of fault tree things. With credible knowledge source and scientific reasoning, the expert system is practical and widely applicable.
