Abstract
A method for operating a radar apparatus having transmitting antennas and at least one receiving antenna, including: generating transmission spectra by complex modulation of mutually equidistant orthogonal OFDM subcarriers; transforming the transmitted spectra into the time domain; digital/analog conversion, high-frequency modulation of the transmitted spectra, and simultaneous emission of the modulated transmitted spectra via the transmitting antennas; demodulating and digitizing a received signal; generating one received spectrum per transmitted spectrum, a division of the OFDM subcarriers corresponding to their division in the transmitted spectra being carried out; eliminating the transmitted signal forms of the transmitted spectra from the received spectra; generating one radar image per received spectrum; evaluating the radar images in a distance dimension and in a speed dimension; and carrying out a signal evaluation for the received signal.
