Abstract:
1. An automotive radar system operable to determine a sweep pattern to be transmitted as an output radar waveform in a multiuser transmission environment, the system comprising: a receiver operable to receive noise signals comprising burst noise, frequency chirp signals generated by one or more other users in the environment, or a combination thereof; a signal generator operable to generate a plurality of different frequency sweep signals; a signal combiner operable to combine each frequency sweep signal with a received noise signal to generate a combined signal for each frequency sweep signal; an interference classifier operable to identify combined signals corresponding to one or more received noise signals comprising frequency chirp signals and to determine the respective noise levels of the identified combined signals corresponding to one or more received noise signals comprising frequency chirp signals; a selector operable to select a plurality of frequency sweep signals in dependence upon the noise levels determined by the interference classifier; and a control unit operable to determine a sweep pattern comprising the selected plurality of frequency sweep signals to be transmitted as an output radar waveform.
