1. A radar device comprising:
a controller comprising a processor and a memory,
a radiofrequency module comprising a plurality of transceivers adapted for transmitting or receiving electromagnetic waves,
a plurality of waveguides, each waveguide of the plurality of waveguides being coupled at a first end of said waveguide to one transceiver of the radiofrequency module, for transmitting or receiving an electromagnetic wave to or from said waveguide,
a plurality of antenna modules, each antenna module of the plurality of antenna modules being coupled at a second end of each waveguide, for transmitting or receiving the electromagnetic wave between the waveguide and said antenna module, and
each antenna module having a controllable electromagnetic surface illuminated by the electromagnetic wave to or from the waveguide,
wherein:
the controller is connected to the radiofrequency module via a data link to exchange wave data with said radiofrequency module, so that each transceiver can transform said wave data into the electromagnetic wave or transform the electromagnetic wave into wave data,
the controller is connected to each antenna module via an antenna link to apply antenna parameters to each antenna module for tuning the controllable electromagnetic surface of each antenna module, and
the controller is scanning a field of view (FOV) in front of the antenna modules by applying successively a plurality of antenna parameters to each antenna module of the plurality of antenna modules.
