Automatic radio environment test platform based on Labview and third-party driving program

Abstract

Disclosed is an automatic radio environment test platform based on Labview and a third-party driving program. The platform is respectively composed of three parts, i.e., an antenna control rotary table, a total control computer and a frequency spectrograph, wherein the total control computer is respectively connected with an antenna rotation platform and the frequency spectrograph. A control program integrated in the total control computer comprises two sub-modules, i.e., a real-time antenna rotation platform control sub-module and a frequency spectrograph control sub-module, wherein the real-time antenna rotation platform control module issues a current orientation and a pitch value through a serial port to the antenna rotary table, and the frequency spectrograph control module connects the total control computer with the frequency spectrograph through a network line and has the functions of arranging observation parameters controlling the frequency spectrograph and reading observation data. The automatic radio environment test platform provided by the invention has the advantage of operation visualization, convenient data recording, simple operation and easy field operation.

Description

technical field [0001] The invention relates to the field of radio frequency spectrum monitoring, and is applicable to fields such as field automatic radio environment measurement, site selection of large radio astronomical telescopes, and the like. technical background [0002] With the development of electronic technology, radio astronomy equipment gradually replaced the original analog terminal by digital terminal. This greatly improves the efficiency of radio astronomy observations, and almost the entire radio frequency band above the radio window is included in the scope of radio astronomy observations. However, with the rapid development of informatization in the whole society, more and more radio frequency bands are used. Therefore, Radio Frequency Interference (RFI) has increasingly become a factor that seriously plagues radio astronomy observations, and even affects radio astronomy observation bands. to fatal impact. Radio interference mainly affects radio astrono...
