1. A method for reducing antenna boresight error, comprising:

  • receiving a plurality of radar pulses reflected from an object, a pulse of the plurality of pulses being emitted from an antenna of a radar system, reflected by the object, and received by the antenna, the plurality of pulses carrying information about the object;

    establishing a plurality of measurement indices from the information carried by the plurality of pulses;

    generating a clutter spectrum from the information;

    measuring an amplitude of the clutter spectrum at each of the measurement indices;

    establishing if there is an amplitude imbalance in accordance with the measured amplitudes; and

    determining an error estimate if there is an amplitude imbalance, the error estimate describing an antenna boresight error of the antenna.
