| Abstract | Abstract — Reflections in antenna test ranges can often constitute the largest single term within the error budget of a given facility [1]. For some time, a frequency domain measurement and post-processing technique named Mathematical Absorber Reflection Suppression (MARS) has been successfully used to reduce range multi-path effects within spherical near-field and far-field antenna measurement systems [2, 3, 4]. More recently, a related technique has been developed for use with cylindrical near-field antenna measurement systems [5, 6, 7]. This paper provides an introduction to the measurement techniques and a description of the novel near-field to far-field transform algorithms before presenting preliminary results of actual range measurements of a low gain antenna taken using a combination spherical / cylindrical system that was installed within a partially anechoic chamber. These results illustrate the success of the techniques which are found to provide comparable improvements yielding far-field patterns that are in encouraging agreement despite every step within the data acquisition, transformation and post-processing chain being different thereby providing further compelling evidence of the success of the MARS technique.
