1. A device for detecting objects borne by immobile or moving individuals, comprising at least:

  • one rotary antenna including at least two parallel rectilinear waveguides and a cylinder provided with a helicoidal slot rotatably movable about said guides, which guides are open facing the interior face of said movable cylinder, said surface forming a microwave short-circuit in order to close said guides, one of said guides being dedicated to emission, a movable radiating source being located facing said guides subsequent to the rotational movement of said cylinder inducing a movable emission and reception beam able to be oriented towards an individual;

    one radar emitting a continuous wave microwave signal towards the emission guide of said antenna and receiving the signals received from the guides of said antenna, which signals are captured by said movable beam, said received signals being the direct component I and the quadrature component;

    one stereoscopic video camera that is oriented in the same direction as said movable beam and able to record the clothing envelope of said individual, said envelope serving as a reference surface for the measurement of distances to said device;

    one processor that computes an SAR image of that portion of the body of said individual which is targeted by said radar and said video camera and who is possibly equipped with one or more objects, from signals received from said radar and the distances measured by said video camera.
