Abstract :
For some time now, a technique named Mathematical Absorber Reflection Suppression (MARS) has been used successfully to identify and then suppress range multi-path effects in spherical [1, 2, 3, 4], cylindrical [5, 6, 7], and planar [8, 9] near-field antenna measurement systems. This paper details a recent advance that, for the first time, allows the MARS measurement and post-processing technique to be successfully deployed to correct antenna pattern data taken using direct far-field or compact antenna test ranges (CATRs) where only a single great circle cut is acquired. This paper provides an overview of the measurement and novel data transformation and post-processing chain that is utilised within the far-field MARS (F-MARS) technique to efficiently correct far-field, frequency domain data. Preliminary results of range measurements that illustrate the success of the technique are presented and discussed.
