Estimating Multiple-Reflection Uncertainties in Spherical Near-Field Measurements



Michael H. Francis, Jeffrey R. Guerrieri, Katherine MacReynolds, Ronald C. Wittmann


We propose a method to estimate multiple-reflection effects on test-antenna pattern and gain uncertainties in the far field derived from spherical near-field measurements. To estimate these uncertainties we make a near-field measurements on two spheres separated by λ/4. We compare this estimate to that obtained when we select several cuts (using all values of θ but only a few values of φ) from each sphere.
