Abstract

The invention discloses a superheterodyne solar radiometer system for a radio astronomical protection frequency point. The superheterodyne solar radiometer system comprises an analog receiver subsystem, a detection-digital collection subsystem, a calibration subsystem, a time frequency subsystem and a control subsystem, wherein the analog receiver subsystem is connected with the control subsystem via the detection-digital collection subsystem; the calibration subsystem and the time frequency subsystem are respectively connected with the control subsystem. The system has the advantages of less radio interference, large dynamic range, simple structure and the like, is applied to multi-point frequency solar radio flow precision observation, and effectively speculates a spatial weather event via observation data.

Description

technical field [0001] The invention belongs to radio astronomy solar power radiometer system technology, which works in the radio astronomy protection frequency band, and uses technologies such as amplification, gating, down-conversion, wave detection, analysis and other technologies for these frequency band signals to observe the total flow of solar radio multi-frequency bands. Multi-band flux variation can play a role in solar physics research, space weather warning and other fields. Background technique [0002] The sun is the closest star to the earth. While it transmits light and heat to the earth, its activities also affect human production, life and technological systems that are increasingly dependent on human beings in various aspects. [0003] A solar eruption is a violent energy release process that occurs in the solar atmosphere-corona. The main forms are solar flares and coronal mass ejections (CME), which are essentially the result of the interaction between m...
