  • article-nadc广州大学NADC大湾区分中心团队 基于卷积神经网络提出新的射频干扰识别方法
    本研究基于深度神经网络对SKA1-LOW的仿真数据以及SKA先导阵列LOFAR、MeerKAT观测数据中的射频干扰(RFI)进行识别，并将识别结果与当前主流的RFI识别算法AOflagger进行对比。
    本次工作利用SKA模拟、校准和成像算法库(RASCIL)结合美国氢原子再电离时代阵列HERA的RFI模拟方法生成受到干扰的SKA1-LOW模拟观测数据，并使用以部分模拟数据训练得到的卷积神经网络（图1） ...
    来对其余三个受到不同强度、形态干扰的数据集进行测试，测试结果表面：本文提出的模型对SKA1-LOW的仿真数据中RFI的识别效果良好，ROC曲线下的面积(AUC)达到了0.93。
