Abstract

Procédé de détection de geste utilisant un signal radiofréquence retour (SRr(t)) qui correspond à la réflexion, sur une cible, d’un signal radiofréquence émis (SRem(t)), le procédé comportant les étapes suivantes : a/ détermination d’un déphasage entre le signal radiofréquence émis (SRem(t)) et le signal radiofréquence retour (SRr(t)), pour une pluralité d’instants d’échantillonnage ; b/ pour une pluralité d’instants d’échantillonnage consécutifs, calcul d’une valeur courante de différence de phase δΦ(t), définie par :  δΦ(t)=Φ(t)-Φ(t-Δt), avec Φ(t) et Φ(t-Δt) les valeurs du déphasage à un instant d’échantillonnage t, respectivement t-Δt, chaque valeur courante de différence de phase δΦ(t) traduisant une valeur courante d’un déplacement de la cible. L’invention permet de mesurer un mouvement par détection radar, sans algorithme complexe ni matériel coûteux. Figure 1
