摘要
An automotive radar system is disclosed that comprises an interference classifier 203 for determining a type of interference in a signal received from a multiuser environment. A sweep pattern comprising frequency sweep signals for a transmitted radar waveform is then advantageously determined in dependence upon the level of interference experienced by frequency sweep signals for the determined type of interference. The automated radar system comprises: a receiver 102 operable to receive a noise signal comprising burst noise, frequency chirp signals generated by one or more other users, or a combination thereof; a signal generator 109, 110 operable to generate a plurality of different frequency sweep signals; a signal combiner 104 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 203 operable to identify combined signals corresponding to received noise signals comprising frequency chirp signals and to determine the noise levels of said combined signals corresponding to received noise signals comprising frequency chirp signals; and a selector 206 operable to select a plurality of frequency sweep signals in dependence upon the noise level determinations by the interference classifier 203 on the combined signals corresponding to received noise signals comprising frequency chirp signals; and a control unit 206 operable to determine a sweep pattern comprising the selected plurality of frequency sweep signals to be transmitted as an output radar waveform.
