1. A method of calibrating a boresight of a radar antenna in a radar system, comprising the steps of:

  • a) selecting a calibration target for use in calibrating the antenna boresight;

    b) obtaining an initial measurement of the target range and azimuth angle at a first time instance;

    c) obtaining a subsequent measurement of the target range and azimuth angle at a second time instance;

    d) calculating a boresight offset angle α

    using the initial and subsequent target range and azimuth angle measurements; and

    e) calibrating the antenna boresight to compensate for the boresight offset angle calculated in step (d).
