当考虑结果的可接受性时,仿真结果的不确定性分析(UA)是必不可少的。本文介绍了一种改进的广义多项式混沌展开(gPCE)方法,用于探地雷达模型中的不均匀性分析。采用辅助微分方程时域有限差分法结合广义四阶有限差分法对二维色散和有耗介质参数的不确定性引起的模拟结果的不确定性进行量化。新方法的结果与蒙特卡罗方法进行了比较。新方法在计算量和速度上都显示出相当大的优势。
The uncertainty analysis (UA) in simulation results is essential when the acceptability of the results is considered. This letter introduces an improved intrusive generalized polynomial chaos expansion (gPCE) method for UA in ground-penetrating radar modeling. The uncertainty in simulation results induced by the uncertain parameters of two-dimensional dispersive and lossy media is quantified with the auxiliary differential equation finite-difference time-domain method combined with gPCE. The results from the new method are compared against the Monte Carlo method. The new method shows its considerable advantage in the computational expense and speed.
