A device comprises at least: one rotary antenna including at least two parallel rectilinear waveguides; a radar emitting a continuous-wave microwave signal towards the emission guide of the antenna and receiving the signals from the guides of the antenna, which signals are captured by the movable beam, the received signals are the direct component I and the quadrature component; a stereoscopic video camera oriented in the same direction as the movable beam of the rotary antenna and able to record the clothing envelope of the individual, the envelope serving as a reference surface for the measurement of distances to the device; a processor that computes an SAR image of that portion of the body of the individual targeted by the radar and the video camera and who is possibly equipped with one or more objects, from signals received from the radar and the distances measured by the video camera.
