Abstract

The invention relates to a device (1) for characterising the actimetry of a subject in real time, having a radar (2) transmitting and receiving radar signals and having a software interface for configuring the form of the transmitted signal; means (3) for processing and computing which are connected to the radar (2) and have a classifier (3a) trained using a database, the means (3) for processing and computing being configured to perform, in real time: - acquisition of colour micro-doppler images (6) having a plurality of colour channels (R, V, B), each having micro-doppler signatures (6a) with colour pixels the value of which depends on a reflectivity and a speed of the subject; - processing of the micro-doppler images (6) to compute an image which is referred to as monochromatic and has monochromatic pixels, each having a given monochromatic intensity, from the colour pixels of each colour micro-doppler image; - transformation of the monochromatic image into a binary image through segmentation, according to an 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 relative to the threshold.
