A system comprises a multifunction radar receiver that in turn comprises processing circuitry and front-end circuitry. The front-end circuitry is operable to receive a millimeter wave burst via a plurality of antennas to generate a plurality received signals. The processing circuitry is operable to receive a first scene representation that is an aggregate of scene representations generated by one or more other radar receivers. The processing circuitry is operable to process the received signals to generate a second scene representation. The processing circuitry is operable to compare the first scene representation and the second scene representation and generate a difference scene based on the comparison. The processing circuitry is operable to generate a control signal based on the difference scene.
