METHOD FOR OPENING A DOOR OF A MOTOR VEHICLE BY MOVEMENT DETECTION, USING A DOPPLER RADAR AND ASSOCIATED DETECTION DEVICE

Disclosed is a method for opening a door of a motor vehicle equipped with a device with two Doppler radars for detecting a predetermined movement of a part of the body of a user, the method including: for each radar, comparing the characteristic parameter with a predetermined shape including a predetermined number of peaks a characteristic value of which is higher than a predetermined persistence threshold; if the characteristic parameter has, for the first and second radars, the predetermined shape in a given interval of interest, and if, in the interval of interest, the first radar also sees a predetermined number of changes of phase between the in-phase component and the phase-offset component, then, the predetermined movement is detected and the door is opened, the door otherwise not being opened.
