Nostradamus radar system. This transhorizon radar system was developed by the National Office of Aerospace Study and Research (ONERA) in France. The system is composed of 288 conical antennae,positioned over three 400 metre-long branches. The transmission and reception components are buried underneath the system. 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 | |
