摘要

结合电场积分方程的Rao-Wilton-Glisson矩量法，评价了几种廉价的局部误差估计技术的性能。对18个完全传导的测试目标的结果用于评估估计器的性能。其中两个估计器产生的误差图始终显示出与参考解的高度相关性。这些估计器也适用于二次量的“目标导向”估计，例如识别对目标雷达横截面误差最大的单元。

Performance of Inexpensive Local Error Estimation Techniques for Integral Equation Numerical Solutions

The performance of several inexpensive local error estimation techniques is evaluated in connection with the Rao-Wilton-Glisson method of moments numerical solutions of the electric field integral equation. Results for 18 perfectly conducting test targets are used to evaluate the performance of the estimators. Two of the estimators produce error maps that consistently exhibit high correlations with reference solutions. These estimators are also suitable for “goal-oriented” estimation of secondary quantities, such as identifying cells that contribute the most error to the radar cross section of the target.
