新一代天气雷达故障处理和故障标准化平台的研发与应用

新一代天气雷达是一个组成结构复杂的探测平台,各个组合之间比较分散。由于机械运转的持续性,且对运行环境要求严格,所以雷达系统易发故障。对不同类型的雷达故障进行归纳和简析,并进行归类,按照雷达故障产生的原因分类为:雷达部件故障、软件故障、灾害引起的雷达故障、虚假报警、雷达产品图像错误。天气雷达故障处理和故障标准化平台的开发将相应的成果应用于日常的气象探测设备的监控业务中,并集成到综合气象观测系统运行监控平台,以实现天气雷达故障的快速响应和维修。对2007年6月至2010年5月新一代天气雷达的运行能力进行了计算,并抽样其中2种型号的天气雷达,对故障案例进行分析研究,给出了故障的分系统分布情况。

Development and Preliminary Applications of a Radar Failure Analysis and Standardization Platform

The new generation weather Doppler radar is a complex construction system.The radar breaks down because of its continuous running and strict environment requirements.The various failures of the radar system are summarized and classified.Based on the failure cause classification,the failures are sorted into 5 categories：（1） hardware malfunction;（2） software collapse;（3） the failures induced by natural disaster;（4） false alarm;and（5） false radar image.A radar failure analysis and standardization platform is developed,aiming at the rapid repairing of the radar failures.The operation capacity of the new generation weather Doppler radar from June 2007 to May 2010 is calculated.Two kinds of radar failures are discussed and the distribution of the radar sub-system failures is given.
