Radio and Submillimeter Astronomy: Radio Telescopes

Part of the UNITEXT for Physics book series (UNITEXTPH)


Radio astronomy, the first astronomy after the optical one, investigates the radio emission of celestial sources. This chapter discusses the receiver systems based on the superheterodyne technique, investigating the different components: antennas, amplifiers, mixers, and detectors. The faintness of the radio signals demands radio telescope systems with high amplification factors.
