A circular synthetic aperture imaging technique for evaluating the performance of antenna far-field test ranges is presented. Using multifrequency data, the fields incident on the region occupied by the scanning antenna are used to produce microwave images showing the distribution and level of scattering artifacts on the test site. Results are presented for S- and X-band ranges on a large outdoor antenna measurement facility. Various primary scatterers are identified, together with a source of secondary illumination of scattering objects.
