1. A method for determining scattering parameters for an operational phased array radar antenna subarray comprising:

  • measuring for a reference subarray that includes a dipole component but not a beamformer component values for a plurality of reference electromagnetic parameters;

    measuring for an operational phased array radar antenna subarray that includes the dipole component and thee beamformer component values for a plurality of operational electromagnetic parameters; and

    calculating from the values for the plurality of operational electromagnetic parameters and the values for the plurality of reference electromagnetic parameters beamformer scattering parameters for the operational phased array radar antenna subarray.
