    • An apparatus for obtaining corrected antenna data includes a processor (40) and a compact range, the corrected antenna data containing co-polarization and cross-polarization properties of an antenna. The compact range defines a quiet zone (QZ) and has a reflector (12) and a feed (16), the reflector being characterized by a paraboloidal shape having a vertex point and focus point, the feed being located at the focus point and being characterized by a feed boresight pointed at the vertex point. The compact range further has a transmitter (20) coupled to the feed and a receiver (30) coupled between the antenna and the processor to provide a received signal to the processor. The processor determines aperture field data from the received signal, the aperture field data containing values based on properties of the compact range and the co-polarization and cross-polarization properties of the antenna. The processor further calculates theoretical field data, the theoretical field data characterizing the properties of the compact range. The processor further combines the aperture field data and the theoretical field data to provide the corrected antenna data.
