## Preliminary Research on RCS Using DGTD

• 摘要: 时域离散伽辽金法(Discontinuous Galerkin Time Domain, DGTD)同时具有时域有限元算法(FiniteElement Time Domain, FETD)非结构网格剖分和时域有限差分算法(Finite Difference Time Domain, FDTD)显式迭代的优点,是一种非常有前途的电磁计算方法,该文首先描述了基于矢量基函数的时域离散伽辽金法的基本原理.然后,给出了DGTD处理散射问题时平面波入射加入的具体实现方法.最后,给出了金属球、介质球和金属弹头宽带散射的算例,算例结果的比较表明了该文算法的正确性和有效性.该文的研究,为复杂目标雷达散射截面RCS的准确预估打下了坚实的基础.
