摘要

现代科学研究，特别是射电天文光谱观测，如果没有合适的软件套件是无法想象的。这是必要的，因为两个原因:1)数据是数字形式的;2)数据处理是一个复杂的多步骤过程。本文利用VIRAC数据处理套件对单台射电望远镜进行空间脉泽观测。描述了软件定义无线电(SDR)后端数据处理。讨论了频率切换算法的实现、观测数据的采集和存储格式。多种方式显示观测结果突出显示。

VIRAC Maser Data Processing Suite

Modern scientific research particularly radio astronomi- cal spectroscopic observations cannot be imagined without appropriate software suite. That is necessary because of two reasons 1) data are in digital form and 2) data processing is a complex multi-step process. In this paper created in VIRAC data processing suite for a single radio telescope, space maser observations are presented. Software Defined Radio (SDR) backend data processing is described. Implementation of the frequency switching algorithm, acquisition of observation data and their format for storing are discussed. Multiple ways to display the observation results are highlighted.
