ABSTRACT:
A boresighting antenna for receiving signals within a given frequency band is covered by a radome having a wall including dielectric material. Boresight error compensation is provided by one or more pairs of perforated metal plates. Each plate has a dielectric material thereon. The plates of each pair are positioned symmetrically in relation to the longitudinal axis of the radome forward of the antenna in the radome in the direction from which the signals are received, and are tilted forward toward the radome axis from the interior wall of the radome at such an angle as to provide a phase lag in frequency components of the received signal at the high end of the given frequency band and a phase lead in frequency components of the received signal at the low end of the given frequency band. Compensation is thereby provided for the boresight error that is caused by the phase shifts of the different frequency components of the received signal that result from the received signal passing through the wall of the radome.
