Christiansen, W. N. and Hogbom, J. © Springer Science+Business Media, LLC 2009, The Principles of Astronomical Telescope Design. In their astronomical role, they differ from optical telescope in that they operate in the radio frequency portion of the electromagnetic spectrum where they can detect and collect data on radio sources. In fact, ), 1976, Astrophysics, Part C: radio Observations, Academic Press, New York. With RYSIA, you can carry out simple observations of objects that radiate brightly in the radio spectrum. Although this is not a fully capable RT, it can provide a wonder - ful learning opportunity for you, or perhaps students in your local school. Whereas optical telescopes study the light wave portion of the spectrum, radio telescopes focus on the radio frequency portion of the electromagnetic (EM) spectrum emitted by almost all astronomical objects. In the first part of this chapter, all the major design issues of radio telescopes are discussed, which include the reflector surface transmission loss, the antenna tolerance theory, the antenna homology design, the antenna surface best fitting, the antenna component positional tolerance, the antenna aperture blockage, the ground radiation pick-up, and antenna best fitting through ray tracing. Emerson, D., 2005, Lecture notes of NRAO summer school on radio interferometry. Satellite Technology. telescopes are not always constructed in the same exact way. The range of frequencies in the electromagnetic spectrum that makes up the radio spectrum is very large.
