Dual-purpose science popularization system for radio astronomy and amateur radio communication

Abstract

The invention discloses a dual-purpose science popularization system for radio astronomy and amateur radio communication. The system comprises a miniature parabola antenna, an equatorial instrument, a program controlled one-out-of-two switch, more than one low-noise amplifier, more than one power amplifier, a software radio transceiver, a GPS timing antenna and a computer. The system provided by the invention can realize observation of multiple strong source signals of radio astronomy and experience of a radio communication technology, can enable science popularization audience to fully understand knowledge in such two aspects, i.e., radio astronomy science and radio science and is simple in apparatus structure, thereby being suitable for industrial production and market promotion and application.

Description

technical field [0001] The invention relates to a radio science popularization device, in particular to a dual-purpose science popularization system for radio astronomy and amateur radio communication, which is mainly applicable to the field of science popularization education for young students in radio astronomy, radio communication and other technical aspects. Background technique [0002] In the past, human beings could only see the optical image of celestial bodies, but radio astronomy shows people the other side of celestial bodies---radio image. Because radio waves can pass through dust clouds that light waves cannot pass through, radio astronomy observations can penetrate into places that were previously invisible to optical methods. The vast world covered by interstellar dust in the space of the Milky Way was first recognized by people after the birth of radio astronomy. The four major astronomical discoveries in the 1960s: quasars, pulsars, interstellar molecu...

AI Technical Summary

Problems solved by technology

[0004] Due to the sensitivity of human beings to perceive things, more science popularization in optical astronomy has been done at present, such as starry sky shooting at night, observation of sunspots and solar prominences during the day, etc. At the same time, the requirements of the entire technical system are relatively high, and such popular science projects have not been carried out well at home and abroad. With the increasingly widespread use of radio frequency technology systems, how to demonstrate radio astronomy, a broad research field, to the public, from the perspective of popular science Intuitive and quantitative display of the signal processing flow to the public from an intuitive and quantitative perspective, which puts forward new requirements for the new astronomical science popularization platform
