Claim 10:
11. An antenna calibration method for operation of a beam steering radar, comprising:
iteratively optimizing voltage and phase values for a plurality of phase shifters coupled to a plurality of antenna elements in an antenna array in the beam steering radar to determine voltage and phase value pairs that result in a desired gain for the antenna array;
storing the voltage and phase value pairs in a look-up-table in the beam steering radar;
applying a set of voltages from the voltage and phase value pairs to the plurality of phase shifters to generate a set of phase shifts corresponding to the set of voltages in the voltage and phase value pairs; and
radiating a plurality of RF beams with the set of phase shifts at the antenna array,
wherein iteratively optimizing voltage and phase values comprises applying a first set of input voltages to the antenna array to converge on a maximum gain for each power distribution path in the antenna array, wherein the convergence criteria comprises a maximum gain for each power distribution path in the antenna array.
