| Abstract | 快速射电暴(Fast Radio Burst, FRB)是一种偶发的、瞬时射电暴,为了探测到更多的样本进行研究,本文基于多波束接收机开发了一套实时搜寻终端,该系统包括信号采集与处理、单波束信号处理、多波束信号合成与分析、探测结果存储与发布等单元,可以对多路波束信号进行同时采集和分析,利用多波束的信号参考效应消除干扰,提高探测准确率.在某射电望远镜上进行了观测实验,通过捕捉脉冲星的单脉冲信号检验了FRB信号的探测功能,结果表明该终端可实现准确、实时的FRB探测. |
| Other Abstract | Fast radio burst (FRB) is an occasional and instantaneous radio burst. In order to detect more samples for research, this paper develops a real-time search digital backend based on multi-beam receiver. The system includes data acquisition and processing, single-beam signal processing, multi-beam signal synthesis and analysis, detection results storage and distribution. It can collect and analyze multi-beam signals simultaneously. Multi-beam signal reference effect is used to eliminate radio frequency interference and improve detection accuracy. Observation experiments were carried out on a radio telescope. The function of FRB detection was tested by capturing the single pulse signal of a pulsar. The result shows that the digital backend can achieve accurate and real-time FRB detection. |
