摘　　要：针对专家系统在雷达故障诊断中存在的不足,构建了一种人工神经网络和专家系统融合的故障诊断模型,给出了该模型的组成和功能表述,分析了诊断参数的选取方法、知识库的建立过程及神经网络模块结构等,并用实例讨论了诊断方法有效性。aimed at these shorts of the unity expert system in radar fault diagnosis. A new method of neural network interfused with traditional expert system is presented in radar fault diagnosis. The frame and function expression of radar fault diagnosis system based on neural network and traditional expert system are given. The select method of diagnosis parameter and the setting up process of knowledge database and module of neural network are analyzed. The experiment results demonstrate that this method can effectively diagnosis faults.
