Embodiment Construction

[0031] specific implementation plan

[0032] See figure 1 , figure 2 , a solar radio total power radiometer system based on a broadband detection chip in the radio astronomy protection frequency band, which works in the radio astronomy protection frequency band, and filters, gates, amplifies, detects, and analyzes these frequency band signals; the present invention is characterized in that: It is composed of a calibration module and its control unit connected with a radio frequency signal detection unit; where:

[0033] The calibration module and its control unit adopt noise source-50 ohm matching load-solar radiation power source-cold air rotation control observation mode, that is, the noise source passes through the coupler and antenna signal through the microwave switch and amplifier with 50 ohm matching load 1 connection, the amplifier 1 is connected to the radio frequency signal detection unit through a 4-power divider;

[0034] The radio frequency signal detection unit...

Abstract

The invention provides a solar radio total power radiometer system in radio astronomy protection frequency band based on a broadband detection chip. The system works in the radio astronomy protection frequency band and carries out filtering, gating, amplification, detection and analysis on frequency band signals. The system is characterized in that the system is formed by connecting a calibration module and a control unit thereof with a radio-frequency signal detection unit. The beneficial effects of the system are that the system has the advantages that the system receives less radio interference; and compared with a conventional superheterodyne mode, the detection broadband is wider and large in dynamic range, and the structure is simple and the like.

Description

technical field [0001] The invention belongs to radio astronomy solar power radiometer system technology, which works in radio astronomy protection frequency bands, filters, gates, amplifies, detects, and analyzes these frequency band signals for the total flow observation of solar radio multi-frequency bands, through multiple Frequency band flow changes 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] Solar eruptions are violent energy release processes that occur in the solar atmosphere—the corona. The main forms are solar flares and coronal mass ejections (CMEs), which are essentially the result of the interaction between magnetic fields and magnetic fields, magnetic fie...
