Real-time omnibearing scanning radio environment monitoring system

Abstract

The invention relates to a real-time omnibearing scanning radio environment monitoring system. The system comprises a receiving module, a preprocessing module, and a processing module which are used for carrying out the multi-phase filtering of each digital signal, and obtaining a plurality of frequency components corresponding to each digital signal; obtaining multiple groups of direction weight parameters, wherein each group of direction weight parameters comprises multiple direction weight parameters, and each group of direction weight parameters corresponds to each direction; obtaining power spectrum data of each frequency in each direction by using a plurality of frequency components corresponding to each digital signal and the plurality of groups of direction weight parameters; and obtaining the total power spectrum data of an omnidirectional radio signal according to the power spectrum data of each frequency in each direction or the plurality of digital signals. According to the embodiment of the invention, the 360-degree omnibearing radio environment condition can be rapidly measured and evaluated in real time, the short-time radio interference can be rapidly captured, and the radio environment condition can be evaluated in real time, so that the observation data quality is improved.

Description

technical field [0001] The present disclosure relates to the technical field of radio environment monitoring, in particular to a real-time omnidirectional scanning radio environment monitoring system. Background technique [0002] Good sites for radio astronomy telescopes such as FAST are hard-won after long-term radio environment tests. Radio environment monitoring with long-term observation synchronization is the only supporting means for radio telescope receiver update, filter design, observation data evaluation, and interference elimination scheme. At the same time, with the development of radio astronomy itself, more and more new spectral lines are detected that are not in the allocated radio astronomy frequency band. There are other active services in the adjacent frequency bands, so the monitoring, evaluation and protection of the radio broadband environment of radio astronomy stations are particularly important.

Problems solved by technology

[0006] The current radio environment measurement mostly uses a mechanical turntable as a platform solution. Since the mechanical turntable rotates for a certain period of time, it is impossible to obtain the radio interference spectrum from all angles in real time. It is difficult to capture short-term and temporary interference. The data effect of some radio astronomy observations may be affected by these occasional interferences
