摘要
文章利用吉林白山和云南西双版纳(双偏振)两部天气雷达的在线自动标定数据,通过统计指标最大值、最小值、均值、标准差、合格率及不合格数据的数量等方法进行数据的分析和研究,以此查找雷达存在的问题.结果表明吉林白山和云南西双版纳(双偏振)两部天气雷达在运行过程中存在数据缺测、超限等问题.对存在问题进行整改后,标定数据质量有了明显的提升,有效提升了雷达的探测精度.
Abstract
This paper uses the online automatic calibration data of two weather radars,Baishan in Jilin Province and Xishuangbanna in Yunnan Province(double polarization),to analyze and study the data by means of the maximum,minimum,mean,standard deviation,qualified rate and the number of unqualified data,so as to find out the problems existing in radar.The results show that the weather radars of Baishan in Jilin Province and Xishuangbanna(dual polarization)in Yunnan Province have some problems such as data missing and over limit during operation.After correcting the existing problems,the quality of calibration data has been significantly improved,and the detection accuracy of the radar has been effectively improved.
