摘　　要：文章提出一种基于报警评分的气象雷达健康状态监测模型。模型根据历史报警记录和故障记录,对报警信号与实际故障之间的关联关系进行统计分析,根据统计特征对报警信号的重要程度进行量化打分,并将报警评分结果结合专家判断,把雷达的报警信号分为四个等级:NA、LI、HI和KA。根据近一段时间各等级报警信号的发生次数对雷达的健康状态进行评价,从而进行故障预警。采用SA雷达的实际报警和故障数据对模型进行验证,结果表明,利用报警评分和状态评判规则获得的雷达状态评估结果与其实际记录相符,证明该方法具有工程应用的条件。In this paper,a meteorological radar health monitoring model based on alarm score is proposed.According to the historical alarm records and fault records,the model statistically analyzes the relationship between the alarm signal and the actual fault,extracts statistical features to quantify and score the importance of the alarm signal,and according to the alarm score results combined with expert judgment,the radar alarm signal is divided into four levels:NA,LI,HI and KA.The health status of the radar is evaluated according to the number of alarm signals of each level in the recent period of time,so as to carry out fault early warning.The model is verified by the actual alarm and fault data of SA radar.The results show that the radar state evaluation results obtained by alarm score and condition evaluation rules are consistent with the actual records,which proves that the method has the conditions for engineering application.
