A UWB radar device

A UWB radar device having two or more first antennas (3) and comprising:

• a generating and transmitting assembly (5) of a UWB signal comprising a predetermined number of generating and transmitting circuits (10) of a UWB signal;
• a receiving assembly (6) of the UWB signal for processing the received UWB signal;
• and
• at least one processing and control logic unit (8) operatively located downstream of said receiving assembly (6);
• wherein:
• said predetermined number of said generating and transmitting circuits (10) of the UWB signal is lower than a number of said two or more first antennas (3);
• said UWB radar device (1) comprises a first selector (14) operatively connected with at least one generating and transmitting circuit (15) of said generating and transmitting circuits (10) of the UWB signal and with at least two of said two or more first antennas (16) so as to convey the UWB signal generated by said at least one generating and transmitting circuit (15) of said generating and transmitting circuits (10) of the UWB signal mutually to said at least two of said two or more first antennas (16);
• and
• said at least one processing and control logic unit (8) comprises at least one memory unit (18), in which at least one delay and sum algorithm configured for being executed by said at least one processing and control logic unit (8) is stored so as to manage a change of phase of the UWB signals received in said receiving assembly (6).
