  • 本文采用有理逼近中的误差分析方法, 对渐近波形估计的计算结果进行了误差分析, 从而提出了一种有效计算带宽的估计方法, 并构造了一种任意给定频段自适应扫频计算方法. 通过对不同几何形态的三维导体目标、色散介质目标的宽带电磁散射特性进行分析, 并将计算结果与解析解、矩量法逐点计算进行了比较, 验证了此算法的有效性.
    The error of asymptotic waveform evaluation (AWE) is estimated by the error analysis of rational approximation, and an efficient bandwidth estimation approach is finally proposed, which is used to form a new adaptive frequency-sweep analysis algorithm for a given frequency band in this paper. The broadband electromagnetic scattering analysis of three-dimensional (3-D) perfectly electrically conducting (PEC) objects with different shapes is performed, and dispersive dielectric object is considered. The effectiveness of the proposed method is proved by comparing the numerical results with those obtained from the analytical solution and the direct solution.
