Modeling target variability using the SBR technique [radar applications]

In this paper, we presented an approach to predict the statistical moments of radar cross section due to dimensional variability when using the SBR (shooting and bouncing ray tracing) technique. The various sources of dimension variability include manufacturing tolerances and CAD modeling errors due to limited knowledge of the target. Though we derived the first two moments, higher order moments can also be systematically derived using this methodology. This approach can also be extended to other sources of target and sensor variabilities.
