Abstract

An apparatus comprising an antenna array comprising a plurality of antennas to receive a plurality of radar signals reflected by a plurality of objects responsive to a transmitted radar signal; a doppler measurement module to determine, for a first reflected radar signal of the plurality of reflected radar signals, a first doppler measurement indicating a velocity component based on a comparison of the first reflected radar signal to the transmitted radar signal; a phase offset measurement module to determine a first phase offset of the first reflected radar signal received at a first antenna of the plurality of antennas relative to a phase of the first reflected radar signal received at a reference antenna of the plurality of antennas; and a phase offset calibration module to determine, for the first antenna, a first phase offset calibration error based on the first doppler measurement and the first phase offset.
