| Solar radio storm is the energy release phenomenon of the solar eruption,Solar microwave bursts show a sharp increase in solar radiation intensity in the microwave band(~GHz),The microwave section of the solar radio burst carries physical information on the process of the solar explosion,high-energy electron acceleration,and radiation mechanisms,The 2.8 GHz solar flux unit plays an important role in the research of the solar magnetic field diagnosis,high-energy electron acceleration mechanism,and solar flare physics.In addition,the solar flux unit is closely related to the characteristics of high-energy particles and the nature of plasma.At the same time,the monitoring of solar flux unit system plays an important role in the study of the long-term solar activity rules,solar radio forecast models,and new observational technologies related to solar radio bursts.Therefore,the research on the observation system of solar radio storm has important scientific significance and application value.In this paper,we have identified a combination of metamaterial antennas,software radios,and high-performance computers,through consulting a large number of documents and combining domestic and foreign monitoring systems,The scheme is all digital design,with the characteristics of small size,highly scalable,programmable and so on.The solar flux unit monitoring system designed in this paper is composed of metamaterial antenna,software radio board,and high-performance computer.The metamaterial antenna completes the reception of solar radio signals,software radio board mainly completes data collection and preprocessing,and then upload to the computer through USB3.0,complete data storage and real-time spectrum analysis on high-performance computer and it can be displayed in various forms such as spectrum map,Dynamic spectrogram,and injection current curve.At the same time,in order to further study,it is also possible to analyze the stored data offline,and store the results of the analysis in pictures,which is convenient for subsequent researchers to view and analyze.According to the actual needs of the project team,this article observes the 2.8GHz solar flux unit and designs solar flux unit monitoring system.The main work of this paper is as follows:The metamaterial antenna was modeled and simulated,and the antenna was designed and manufactured.The performance of the metamaterial antenna was tested and optimized.Simultaneously with the theory and structural model of software radio,the problems existing in the spectrum analysis of continuous signals are studied,and the optimized algorithms are compared through simulation.Based on the software radio platform,the development and implementation of the spectrum analysis system are carried out,and deign of each module is made.It mainly includes the design and optimization of various modules such as board communication,data acquisition,data storage,real-time spectrum analysis,discrete spectrum analysis,and intensity map storage.The final system was field debugged and operated continuously for a long time and achieved good results.It can provide data support for the observation of solar radiation. |
