A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky. [ 1 ] [ 2 ] [ 3 ] Radio telescopes are the main observing instrument used in radio astronomy , which studies the radio frequency portion of the electromagnetic spectrum , just as optical telescopes are used to ...

The Kraus-type radio telescope design was created by Dr. John D. Kraus (1910–2004).. Kraus-type telescopes are transit instruments, where the flat primary mirror reflects radio waves towards the spherical secondary mirror, which focuses it towards a mobile focal carriage.
The Parkes Radio Telescope, completed in 1961, was the brainchild of E. G. "Taffy" Bowen, ... This primary-secondary approach was designed by Barnes Wallis.
The Reber Radio Telescope is a historic radio telescope, located at the Green Bank Observatory near Green Bank, West Virginia, United States. Built in 1937 in Illinois by the astronomer Grote Reber, it was the first purpose-built parabolic radio telescope. It was designated a National Historic Landmark in 1989. [2] [3]
The Arecibo Telescope was a 305 m (1,000 ft) spherical reflector radio telescope built into a natural sinkhole at the Arecibo Observatory located near Arecibo, Puerto Rico.A cable-mount steerable receiver and several radar transmitters for emitting signals were mounted 150 m (492 ft) above the dish.
John Daniel Kraus (June 28, 1910 – July 18, 2004) was an American physicist and electrical engineer known for his contributions to electromagnetics, radio astronomy, and antenna theory. His inventions included the helical antenna , the corner reflector antenna , and several other types of antennas.
