Radio and Submillimeter Astronomy: Radio Telescopes
2016Radio 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

Antennas in Radio Telescope Systems
2015Radio astronomy is the study of the universe by measurement of radio frequency emission at frequencies ranging from a few MHz to the far infrared. Signals of interest are typically extraordinarily weak, necessitating large effective aperture and resulting in some of the world’s largest antenna systems.
