RADAR DEVICE FOR A MOTOR VEHICLE AND METHOD FOR CONTROLLING THE DEVICE

A radar device for a motor vehicle comprises a radar antenna configured to detect a reflected signal characterized as a reflection of a transmitted signal reflected by an object present in the field of view of the radar antenna; a controller configured to transmit at least one radar signal from the radar antenna, the radar signal being transmitted according to a determined object detection transmission power; the controller being configured to detect the power level of the reflected signal derived from the transmitted radar signal reflected by the detected object; the controller being configured to adjust the transmission power, according to the power level of the reflected signal detected, to a minimum power sufficient for the detection of the detected object.
