摘要
针对星载TWTA(TraveulingWaveTubeAmplifier)的PCB(PrintedCircuitBoard)可靠性检测及故障诊断问题引入了非接触式的红外热像检测方法 ,介绍了其应用的理论依据 .然后 ,应用数理统计理论和矩阵范数理论提出了一个基于红外热像技术的PCB可靠性检测模型 .并在此基础上给出了一个基于事例库的故障诊断方案 .最后 。
Infrared thermal imaging technique, a new non-contact detection method, was introduced into reliability detection and faults diagnosis of spaceborne TWTA and its detection principle was also presented. Then, a new effective model, which basess on methematical statistics and matrix norm theory and uses infrared thermal imaging technique, was put forward for PCB reliability detection. On the basis of the model, a PCB faults diagnosis method, which bases on examples database, was advanced. Finally, applications of the PCB reliability detection model and faults diagnosis method to spaceborne TWTA were presented.
