| 摘 要： | 本文研究了复合激励方法在电磁散射计算中的应用,此方法首先分析地面的散射,再将地面的散射与入射波一起作为激励作用于目标,从而得到目标的电磁散射信号.文章分析了地表背景下车体的电磁散射,计算了目标的RCS和SAR成像,并与试验作了对比,两者吻合较好.

| Abstract: | A model called composite excitation method for targets upon ground in the application of electromagnetic scattering computation is described.The method comprises two steps:first calculates the scattering of ground,second step calculates the scattering of targets by imposing the scattering wave got at first step upon the targets.A truck is concerned in this paper.The scattering waves、 RCS in UHF frequency and SAR imagining are calculated.Good agreements between calculated and experimental results are obtained.It shows the effectiveness of the method. |
