For a little over a decade now, a measurement and post-processing technique named Mathematical Absorber Reflection Suppression (MARS) has been used successfully to identify and then suppress range multi-path effects in spherical, cylindrical &p; planar near-field antenna measurement systems and far-field and compact antenna test ranges with a detailed theoretical treatment being presented in. Much of this early work concentrated on verification by empirical testing however some corroboration was obtained with the use of computational electromagnetic simulations that considered far-field and subsequently nearfield cases. The recent development of a highly accurate computational electromagnetic simulation tool that permits the simulation of “measured” far-field pattern data as obtained from using a compact antenna test range (CATR) has for the first time permitted the careful verification of the far-field MARS technique for a given AUT and CATR combination. For the first time, this paper presents simulated “measured” far-field pattern data in the presence of a large scatterer and then verifies the successful extraction of the scattering artefacts using standard FF-MARS processing. Results are presented and discussed.
