The invention discloses a device () for characterizing in real time the actimetry of a subject, having: a radar () emitting and receiving radar signals, and having a software interface for configuring the shape of the signal emitted; processing and computing means () coupled to the radar (), having a trained classifier () using a database, said processing and computing means () being configured to perform in real time: —a capture of color micro-Doppler images () having several color channels (R, V, B), each having micro-Doppler signatures () with color pixels the value of which is a function of a reflectivity and a speed of the subject; —a processing of the micro-Doppler images () for: computing a so-called monochromatic image having monochromatic pixels, each having a given monochromatic intensity, on the basis of the color pixels of each color micro-Doppler image; transforming the monochromatic image into a binary image by segmentation, according to a binary luminous intensity threshold, of the monochromatic pixels, producing binary pixels, the value of which is dependent on the chromatic intensity of the monochromatic pixel associated with the binary pixel, with respect to the threshold.
