Nostradamus radar system. Juanito Munoz, tracking specialist at the French National Office of Aerospace Study and Research (ONREA), checking the generators for Nostradamus, a transhorizon radar system. These generators are stored underneath the radar. On the surface, Nostradamus is composed of 288 conical antennae, positioned over three 400 metre-long branches. Nostradamus is capable of detecting aircraft flying 700-2000 kilometres away. The system uses low frequency waves (6-30 MHz), which bounce off the ionosphere (outer layer of the Earth's atmosphere) and allow the radar to detect targets beyond the horizon.
