Experimental spherical near field antenna test facility, phase 2. Volume 1: Facility description and measurement results
Abstract
An experimental facility for spacecraft antennas was developed. An HP1000 minicomputer controls the measurements and performs the near field to far field transformations. Measurements were carried out on an OTS spotbeam reflector antenna and a MARECS circularly polarized horn to qualify the technique. The results indicate that directivity can be predicted to within 0.04 dB. On-axis cross polarization and sidelobe levels are also accurately measured. Measurement of cross polar level is least accurate.
