Nostradamus

Nostradamus (NOuveau Système TRAnshorizon Décamétrique Appliquant les Méthodes Utilisées en Studio) is a French military Over-The-Horizon (Backscatter) radar operating in the HF band, resulting from the STUDIO (Systme de Traitement Universel de Diagnostic IOnosphriques) research project.

The monostatic antenna consists of 288 single bi-conical radiators. They are arranged in Y-shaped three antenna groups, each 384 m long and 80 m wide. Of these, only the individual radiators located within a radius of 120 m are used for transmission. Nostradamus can electronically steer its sounding signal in any direction.

Nostradamus became operational at the beginning of this millennium.
