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

Spectrometers for Radio Telescopes
1999When we decide to build a new radio telescope for observing at millimeter wavelengths of the electromagnetic spectrum, we have to make many very important decisions. One of these is the type of spectrometer to use. Here we will present a short description of the several choices available, with special focus on acousto-optical spectrometers.
