Near-Field Spherical Scanning: Uncertainties in Test-Zone Field Measurements



Randy Direen, Ronald C. Wittmann, Michael H. Francis


The electromagnetic field within a test volume can be measured using spherical scanning techniques. Characterization of the field within the sphere requires compensation for probe-pattern effects. We provide a simple uncertainty analysis to estimate uncertainties associated withthis deconvoltion
