Abstract
A radar unit (400) for detecting an existence of interference is described that includes: a millimetre wave (mmW) transceiver (Tx/Rx) circuit configured to radiate a transmit radar signal and receive an echo signal thereof; a mixed analog and baseband circuit operably coupled to the mmW Tx/Rx circuit; and a signal processor circuit (452) operably coupled to the mixed analog and baseband circuit. An interference detection unit (448) is operably coupled to the mmW Tx/Rx circuit and configured to: monitor a whole or a portion of a radar frequency band supported by the radar unit and identify, from a received interference signal, an arrival direction of the identified interference and a level of interference and output an interference detected signal; and wherein the signal processor circuit (452) is configured to analyse the interference detected signal and quantify a response to the detection of an arrival direction and a level of received interference.
