Abstract
An evaluation device for at least one radar sensor having an electronic unit which is designed to evaluate measuring signals of the radar sensor. The radar sensor is designed in such a way that, during its measuring cycles, it emits radar signals and to receive radar signals reflected from an area surrounding the radar sensor and outputs signals corresponding to the received reflected radar signals as measuring signals, while the radar sensor remains inactive for a predetermined pause time between two successive measuring cycles. The electronic unit is designed to perform a Fourier transform utilizing measuring signals from at least two different measuring cycles and/or utilizing evaluation signals derived from the measuring signals from at least two different measuring cycles. A corresponding method for evaluating at least one radar sensor is also described.
