摘要：

This work presents a first-order treatment of aberrations caused by small feed displacements in classical axially-symmetric dual-reflector antennas. A general and closed-form analysis (based on geometrical optics principles) of the aberrated aperture field is derived in terms of the reflector geometry and feed illumination. The consequences to the aperture efficiency and main-beam tilt are illustrated for axially-displaced-ellipse configurations.
