  "textContent": "Disclosed is a method for opening an opening element of a motor vehicle having a device detecting a predetermined movement of a user's body part, including a Doppler radar, including an antenna, radar waves transmitter/receiver and a radar wave processor. The method includes detection modes and standby modes with reduced wave frequency, the method including during standby: Phase demodulating the reflected radar waves and determining a first signal representing a phase variation of the reflected waves over time; Phase-shift demodulating the reflected radar waves, and determining a second signal representing phase variation of the reflected waves shifted as a function of time; Comparing threshold to maximum value of the absolute values for the first and second signals; Exiting the standby mode and triggering the detection mode if the maximum is greater than the predetermined threshold; Opening the opening element if the predetermined movement is detected during the detection mode.",
