摘　　要：本文将专家系统技术和天线阵的“外监测”方法结合起来，建立了微带天线阵的故障诊断专家系统．专家系统以故障点与外场信号之间的关系作为专家知识，采用似然推理方法进行故障诊断，从而替代了人工故障诊断．模拟诊断结果表明专家系统具有速度快、准确率高等优点．The technique of the expert system is combined with the out side monitor method of the antenna arrays to build a fault diagnosis expert system for the microstrip antenna arrays. According to the deviation of the distant field resulting from the fault of the microstrip antenna arrays, the expert system can find the fault by the reasoning method with uncertainty instead of artificial diagnosis. The result of simulated diagnosis shows that the process of the expert system is fast and accurate.
