Radio Environment Monitoring Software Based on LabVIEW Platform

摘要: 本文介绍了一种基于LabView的控制频谱仪无线电环境监测软件。针对射电天文台址无线电环境勘选和监测的要求，本软件在频谱仪设计方面充分考虑到了射电天文微弱信号特点，针对弱信号长时积分、任意精细化监测带宽设置、动态信号频谱瀑布图显示以及多种数据记录等诸多要求设置了软件功能。在数据管理方面，以“年月日时分秒”的文件名命名规则记录观测信号的最大值和平均值，方便回溯和分析干扰数据。经实际对射电天文台址无线电环境监测后，实现了对0~26.5 GHz频段的无线电环境数据自动获取监测，并将投入长期的射电天文台址无线电环境的监测工作。

Abstract: This paper introduces a control spectrum analyzer radio environment monitoring software based on LabView. According to the requirements of radio environment prospecting and monitoring of radio observatory sites, the software takes full account of the characteristics of weak radio astronomy signals in the design of the spectrometer and sets up software functions for many requirements such as long-term integration of weak signals, arbitrary fine-tuned monitoring bandwidth Settings, dynamic signal spectrum waterfall display, and various data recording. In terms of data management, the maximum value and average value of the observed signal are recorded with the filename naming rule of “year, month, day, hour, and second”, which is convenient for back- tracking and analyzing interference data. After the actual monitoring of the radio environment of the radio observatory site, the automatic acquisition and monitoring of the radio environment data in the band of 0~26.5 GHz has been realized, and the long-term monitoring of the radio environment of the radio observatory site will be put into use.
