Radio Astronomy (Radio Astronomie)

1991
Aperture Synthesis Telescopes — Commissioning tests and observations have been made using three antennas in the Australia Telescope (AT), spaced up to 2km apart, and the first image of a radio source observed at 6cm was produced in 1989. The IRAM millimeter array in France comprizing three 15-m antennas has been commissioned at 3mm. A fourth antenna is

Radio logicielle, radio cognitive

2013
Il y a 20 ans déjà que la radio logicielle a été définie conceptuellement dans l’article fondateur de Joe Mitola III de 1995 sur la “software radio architecture” paru dans l’IEEE Communications Magazine. Comme c’est souvent le cas dans les secteurs technologiques, les militaires (DoD, Department of Defense des Etats-Unis) ont été précurseurs dans le ...
