CALIBRATION OF A MULTIFUNCTIONAL AUTOMOTIVE RADAR SYSTEM

Abstract:

A multifunctional radar transmitter may comprise bus interface circuitry and beamforming circuitry. The beamforming circuitry, with use of a plurality of beamforming coefficients, is operable to process a plurality of baseband signals to generate a millimeter wave radar burst corresponding to a radiation pattern that comprises a first lobe and a second lobe, where the first lobe is at a first angle and the second lobe is at a second angle. The bus interface circuitry is operable to receive, from a first receiver, an indication of interference from the second lobe present at the first receiver. The beamforming circuitry is operable to adjust, based on the indication of interference, the beamforming coefficients such that the second lobe is redirected to a third angle.
