基于SE-UNet的天气雷达电磁干扰杂波识别技术OA
Indentification of weather radar electromagnetic interference clutter based on SE-UNet model
天气雷达观测中因电磁干扰杂波造成的质量问题占其所有数据质量问题的90%以上,这些虚假回波处理进基数据后,将对降水估测、反演及外推等资料应用带来较大误差.为更好地识别该类异常回波并采取控制措施以保证天气雷达观测数据质量,本文采用深度学习语义分割思路,在U-Net模型基础上,引入SEBolock模块,构建了针对天气雷达电磁干扰杂波识别的SE-UNet模型.经分析验证,SE-UNet模型的平均像素精度(Mean Pixel Accuracy,MPA)和平均交并比(Mean Intersection-over-Union,MIoU)都达到了 99.9%,均高于 SegNet、LinkNet 和 U-Net 模型的训练结果,且损失率Los值最低.表明该模型在电磁干扰杂波与降水分割方面具有较高的可靠性.
The data quality issues caused by electromagnetic interference clutter account for more than 90%of all data quality problems in weather radar observations.Whenever these false data being incorporated into the base data,will introduce significant errors in precipitation estimation,backscatting analysis,and extrapolation of meteorological data.To better identify these abnormal echo returns and implement control measures to ensure the quality of weather radar observation data,this paper proposes an improved semantic segmentation approach based on deep learning,incorporating the SEBolock module into the U-Net model architecture to establish a new model,the SE-UNet model,for identifying electromagnetic interference clutter in weather radar.Based on the analysis and validation,the Mean Pixel Accuracy(MPA)and Mean Intersection-over-Union(MIoU)of the SE-UNet model both reached 99.9%,surpassing the performance metrics of SegNet,LinkNet,and U-Net models,which also having the lowest loss rate(Los).This indicates that the proposed model demonstrates high reliability in distinguishing electromagnetic interference clutter from precipitation returns.
