Patent attributes
An automotive radar system to determine a sweep pattern to be transmitted as an output radar waveform in a multiuser transmission environment is disclosed. The system includes: a receiver to receive noise signals; a signal generator to generate a plurality of different frequency sweep signals; a signal combiner to combine each frequency sweep signal with a received noise signal; an interference classifier to identify combined signals corresponding to one or more received noise signals including frequency chirp signals and to determine the respective noise levels of the identified combined signals corresponding to one or more received noise signals including frequency chirp signals; a selector to select a plurality of frequency sweep signals in dependence upon the noise levels determined by the interference classifier; and a control unit to determine a sweep pattern comprising the selected plurality of frequency sweep signals to be transmitted as an output radar waveform.
