Abstract
Methods and systems are disclosed and include receiving a signal via a first communication channel at a plurality of azimuth angles. The method includes determining a plurality of first communication channel phase angle differences between a pair of antennas. The method includes receiving a second signal via a second communication channel and at the plurality of azimuth angles. The method includes determining a plurality of second communication channel phase angle differences between the pair of antennas that each correspond to one of the plurality of azimuth angles. The method includes generating a first reference curve based on the plurality of first communication channel phase angle differences. The method includes generating a second reference curve based on the plurality of second communication channel phase angle differences. The method also includes generating a calibration curve that is based on an interpolation of the first reference curve and the second reference curve.
