Abstract
A method for detecting the environment of a motor vehicle utilizing a radar system includes bringing about frequency modulation utilizing an oscillator and generating a sequence of transmission-frequency-modulated transmit signals, which each having the same nominal frequency profile, apart from a variation in frequency position. Received signals for object detection are evaluated. A one time-discrete signal per transmit signal is used which includes information about the frequency profile of the transmit signal and which is generated by sampling of an analog signal or by reading out of a free-running counter at predetermined points in time. These time-discrete signals are unnormalized by way of the transmit signals with regard to the position of their phase and/or their initial value.
