Abstract
A method for detecting the environment of a motor vehicle utilizing a radar sensor includes bringing about frequency modulation with a controllable oscillator and generating a sequence of transmission-frequency-modulated transmit signals, which each have the same nominal frequency profile. Received signals reflected from objects are evaluated such that an actual profile of the transmission frequency within the transmit signals or a deviation of the actual profile from the nominal frequency profile is established. Depending on an actual profile and/or a deviation determined, correction in the driving of the oscillator and/or correction in the evaluation of the received signals and/or adaptation of the driver assistance function and/or the autonomous driving maneuver function up to and including disabling thereof are performed.
