Abstract
A dome antenna with cross polarization compensation for reducing cross polarization induced monopulse tracking errors controls the polarization at the elements of the feed array to reduce the cross-polarization component in a far field radiation pattern of the antenna. Cross-polarization components at each element in the feed array for a linearly polarized plane wave incident at a predetermined direction to the dome are determined and each element is oriented to be polarized orthogonally to the cross-polarized component at that element.
