Application of Mathematical Absorber Reflection Suppression to Planar Far-Field Antenna Measurements

Authors: S.F. Gregson, A.C. Newell, G.E. Hindman, J. Dupuy, C.G. Parini

For some time now, a technique named Mathematical Absorber Reflection Suppression (MARS) has been used successfully to identify range multi-path effects in spherical, cylindrical, and planar near-field antenna measurement systems. This paper detail 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 utilized 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.
