High-Order Accurate Time-Domain Electromagnetics and RCS Prediction for Dynamic and Uncertain Scatters

Abstract

In this project we have pursued the development of computational ways of quantifying the impact of uncertainties on RCS computation. We present a systematic, accurate, and efficient way of addressing such problem, essentially enabling one to compute with an ensample of data and, subsequently, obtain a full space-time ensample of solutions with an associated probability density. The uncertainties can be present in the sources, the materia1s, or the geometries.
