Device, system and method for real-time detection of fast radio bursts with multi-beam receiver

Abstract

The invention provides a fast radio burst real-time detection device, system and method of a multi-beam receiver. The fast radio burst real-time detection device of the multi-beam receiver comprises asignal processing unit, a high-speed data exchange unit, N computing nodes, a head node and a storage unit. The signal processing unit performs signal acquisition and frequency domain transformationon N channels of beam signals, and outputs N channels of fast radio burst observation data, wherein N is larger than 1. The N computing nodes separately process the N channels of the fast radio burstobservation data exchanged by the high-speed data exchange unit in real time, and separately extract fast radio burst candidates and store the fast radio burst candidates separately. The head node aggregates data of the N computing nodes at the same time according to time information stored in the computing nodes to perform concurrent signal synthesis. The fast radio burst candidates are distinguished for fast radio burst candidate detection and classification. The detection accuracy and efficiency are effectively improved.

Description

technical field [0001] The invention relates to a fast radio burst real-time detection device, system and method of a multi-beam receiver, which is suitable for accurate, efficient, real-time detection of fast radio bursts and related scientific research. Background technique [0002] More than a decade ago, astronomers suddenly received a very high-energy radio burst that lasted only a few milliseconds. Astronomers dubbed it a Fast Radio Burst (FRB), and it was picked up many times later. The unusually high density of electron columns known as dispersion measurements (DM) in the received FRB signals has led to speculation that such signals originate from cosmic distances and / or extreme environments. However, the source of this mysterious signal has remained elusive. [0003] In order to observe and study this phenomenon, many astronomical observatories at home and abroad have established FRB detection systems one after another. At present, the construction is generally b...

AI Technical Summary

Problems solved by technology

At present, the construction is generally based on single-beam receivers. However, due to the small field of view of single-beam, the identification of interference signals can only rely on the electromagnetic environment and limited elimination methods. Not only the detection efficiency is limited, but the identification accuracy is also low.
