论文摘要
射频干扰(RFI)正在威胁现代射电天文学。一种减轻其对天文数据影响的经典方法涉及通过称为标记和空白的过程丢弃损坏的时间和频率数据样本。我们提出了RFI信号的环固化特性的开发,以可靠地检测和预测其在阵列射电望远镜视野中的位置,并动态地安排天文观测,以最大程度地减少RFI数据腐败的可能性。
Radio Frequency Interference (RFI) is threatening modern radio astronomy. A classic approach to mitigate its impact on astronomical data involves discarding the corrupted time and frequency data samples through a process called flagging and blanking. We propose the exploitation of the cyclostationary properties of the RFI signals to reliably detect and predict their locations within an array radio telescope field-of-view, and dynamically schedule the astronomical observations such as to minimize the probability of RFI data corruption.
