Abstract

We have been developing the uncertainty analysis of RCS calibrations and measurements at the Etcheron Valley RCS outdoor ground-bounce facility in the 2-18 GHz range. In this study we report on the results of the uncertainty analysis primarily at 11.3 GHz, but results at some other frequencies are also discussed. We plan to address all components of uncertainty liste in [1], and present here in some detail the procedures used to determine the uncertainties due to nonplanar illumination, drift, noise-background and nonlinearity. We use a measurement-based approaoch to obtain upper-bound estimates for the component uncertainties, which are combined using root-sum-squares (RSS) to obtain the overall uncertainty. The uncertainties at any frequency can be determined using these measurement procedures.
