Abstract
This is a report on work in progress to understand the wide variations in sphere calibration data observed on dynamic radar cross section measurement ranges. The magnitude of these fluctuations indicate an uncertainty of greater than 2 dB in some cases. The range of fluctuations in the received power (which is well beyond fluctuation due to received noise) underlines the need for a through understanding of sources of uncertainties in dynamic radar cross section measurements. In addition to the flucturation, we observe a systematic error with respect to the mean of the data segments, possibly due to drift, pointing errors and / or target-background interactions. Understanding the error mechanisms in these measurements allows us to reduce the overall uncertainty and to improve data quality.Proceedings Title
