ABSTRACT:
A radar sensor having a transceiver device (10, 12), an analog/digital converter (14) for converting the received signals (A) into digital data, a memory device (18) for storing the digital data as a useful data set (D1) which provides the digital data for a recording period as a function of time, a transformation device (16) for calculating a spectrum (S) of the useful data set, and an analyzer (24) for analyzing the spectrum, characterized by a back-transformation device (22) for transforming the spectrum (S) back into a digital comparison data set (D2) and a comparator (20) which is designed for the purpose of evaluating the match between the useful data set (D1) and the comparison data set (D2) and, in the event of a match, conveys the spectrum (S) to the analyzer (24) and in the event of a non-match triggers error handling.
