突破聆听是一项为期10年的计划，旨在寻找外星文明在无线电和光波长创造的技术的特征。在这里，我们详细介绍了在澳大利亚新南威尔士州的64米口径CSIRO帕克斯望远镜上为突破性聆听观测部署的数字数据记录系统。记录系统目前实现两种模式：双极化，1.125 GHz带宽模式的单波束观测，和26输入，308 MHz带宽模式的21厘米多波束接收器。该系统还设计为支持即将推出的Parkes超宽带馈电的3 GHz单波束模式。在本文中，我们提出了详细的系统架构，提供了硬件和软件的概述，并提出了初步的性能结果。
Abstract Breakthrough Listen is a 10-yr initiative to search for signatures of technologies created by extraterrestrial civilisations at radio and optical wavelengths. Here, we detail the digital data recording system deployed for Breakthrough Listen observations at the 64-m aperture CSIRO Parkes Telescope in New South Wales, Australia. The recording system currently implements two modes: a dual-polarisation, 1.125-GHz bandwidth mode for single-beam observations, and a 26-input, 308-MHz bandwidth mode for the 21-cm multibeam receiver. The system is also designed to support a 3-GHz single-beam mode for the forthcoming Parkes ultra-wideband feed. In this paper, we present details of the system architecture, provide an overview of hardware and software, and present initial performance results.
