摘要
针对云南省普洱雷达站新一代天气雷达接收系统出现的一次特殊故障,通过对主要性能指标进行标定和分析,判断雷达接收系统出现故障,并根据接收系统的工作原理和信号流程,运用频谱分析仪对接收系统的各信号频谱进行测试分析,完成故障定位和排除。此次故障排除过程充分体现了频谱分析仪在接收系统故障处理中的重要性。
A special fault in the receiving system of the CINRAD/CC radar at Puer of Yunnan Province is discussed.The calibration and analysis are conducted of the main performance indexes of the radar system.The fault location and elimination was performed through testing and analyzing the spectrum signals from the spectrum analyzer,according to the working principles and signal flow.It proved that a spectrum analyzer is useful in the troubleshooting of CINRAD/CC radar receiving systems.
