摘要 文章将高阶叠层矩量法与渐近波形估计(AWE)法进行结合,用于解决高阶叠层矩量法的宽频带计算时间长的问题。分析结果表明,利用新的方法所得结果与高阶矩量法曲线基本吻合,新方法有效地降低了宽频带的计算时间,而且剖分的单元宽度要大于低阶AWE法,这有利于进一步对电大目标进行宽频带计算。 In this paper,the higher-order hierarchical method of moments(HOH-MOM) is integrated with the asymptotic waveform evaluation(AWE) to resolve the problem that the HOH-MOM spends long computing time in solving broadband.The comparison results show that the curve of the new method and that of the higher-order MOM are approximately consistent.By applying the new method,the computing time of broadband is reduced effectively,and the unit width of partition is larger than that by the ordinary AWE method.This study is helpful for the wide-band scattering calculation of electrically large objects.
