针对传统诊断技术在现代雷达故障诊断中的局限性,结合现代雷达装备的结构及故障特点,采用模糊神经网络专家系统(FNNES)和层次诊断模型相结合的诊断策略,对现代雷达装备进行故障诊断。通过实例检验,该诊断策略具有故障诊断能力强、诊断效率高和较好泛化能力的特点,能有效解决当前雷达故障诊断难题,且适用于其他复杂装备的故障诊断。

In order to overcome the limitation of the traditional diagnosis technology in fault diagnosis of modern radar,a new diagnosis strategy based on the Fuzzy Neural Network Expert System (FNNES) and hierarchical model was introduced according to the characteristics of the modern radar construction and fault features. Fault diagnosis was carried out for modern radars,and the result indicated that the diagnosis strategy could obviously improve the capability and efficiency of fault diagnosis. Further more,this strategy could be applied in fault diagnosis of other complex equipments.
