MODEL RELEASED. 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 | |
