Research of Radar Transmitter Fault Quick DiagnosisBased on Information Fusion

利用单一信息对雷达发射设备进行故障检测和诊断时,可靠性和准确性低。针对雷达发射设备器件温度反映发射机工作性能明显的特点,提出了基于电传感器和温度传感器等多传感器信息融合的快速故障诊断方法。给出了故障诊断中信息融合的模型和算法,讨论了多传感器信息融合的雷达发射设备故障快速诊断系统的组成和简单工作原理。在提高复杂电子装备故障诊断可靠性和准确性上提供了一条有效途径。

When the radar transmitter faults are diagnosed using single sensor, the source of fault information is limited, the accuracy and reliability of fault diagnosis are low. In order to solve this question, taking advantage of the transmitter temperature characteristic, a method of fault diagnosis based on multisensor information fusion is presented. The model and algorithm of information fusion are given, and the structure and principle of fault diagnosis system are described. This system has improved the accuracy and reliability of fault diagnosis, raising the efficiency and provides a new way for fault diagnosis.
