雷达装备智能集成故障诊断

Research on Intelligent Integreated Fault Diagnosis for Radar Equipment

现代雷达装备功能多、结构复杂、集成度高,其故障具有复杂性、层次性、相关性、延时性和不确定性。因此雷达装备故障模式多种多样,信号复杂,单一诊断模式已远远不能满足故障诊断的需要,基于现代雷达故障诊断的复杂性的现时需求,提出雷达装备智能集成故障诊断模型,给出了模型的诊断推理过程,对系统实现中的知识获取、知识表示和诊断推理方法进行了深入研究,该研究可以达到人类专家诊断过程相近的诊断效果,可大大提高雷达装备故障诊断的智能化水平。

Due to the multi-function, complex structure, high integration, its fault has features which is complexity, hierarchical, correlative, time-delayed and uncertain, thus radar equipment fault mode is complex, single mode fault diagnosis can not meet the need for the fault diagnosis, based on the need of complexity of modern radar fault diagnosis, paper puts forward the radar equipment intelligent integration fault diagnosis model, gives the diagnosis reasoning process of the model, gives a detailed research on knowledge obtaining, knowledge representation and diagnosis reasoning method of system realization, the research can attain a diagnosis effect closed to the human expert＇s diagnosis process and greatly enhances the intelligent level of radar equipment diagnosis.
