Reflector Surface

The IRAM 30m Millimeter Radio Telescope MRT

Radio Telescope Paul Allen

In chapter one we mentioned that the development of large reflector antennas has been spurned strongly by the needs of radio astronomers. Interestingly, this is not entirely the case for the spectral range, called millimeter-wave radio astronomy, which we define as the frequency range from 30 - 300 GHz (wavelength 10 to 1 mm). The first reflectors, sufficiently accurate to operate at 3 mm wavelength, were the 4.9 m diameter antenna at the University of Texas (Tolbert et al.,1965) and the 4.6 m...
