摘要
以空间无限长导体圆柱雷达散射截面(RCS)的数值计算为例,分析、研究了时域有限体积(FVTD)方法在电磁场数值计算中的应用方法,通过对不同散射条件下RCS的计算,并对数值计算结果进行了较为深入的分析。结果表明,计算结果与解析结果吻合较好。
With the numerical calculation of radar cross section (RCS) of a perfectly conductive circular cylinder in free space as an example, the application of FVTD( Finite Volume in Time Domain) in Computational Electromagnetism (CEM) is discussed. The RCS values under the different scattering conditions are calculated and thoroughly analyzed. The results show that the calculated RCS has very good agreement with the theoretical value.
