Future radio telescopes will be used by astronomers to make high-sensitivity wide-band and wide-field surveys of the radio sky. A candidate technology to provide these expanded capabilities is to place high-sensitivity phased-arrays at the focal plane of reflector antennas. Since this technology has not been proven yet, we have constructed the PHased-Array feed Demonstrator (PHAD) with the goal of exploring engineering aspects of this new technology. PHAD comprises 180 densely-packed Vivaldi… CONTINUE READING
