| 摘 要： | 研究了强迫激励方法在电磁散射计算中的应用 ,此方法将地表目标散射分析化为两步 :首先分析地面的散射 ,再将地面的散射作为激励作用于目标 ,从而得到地面背景下目标的电磁散射信号。应用强迫激励方法计算了地表背景下车体的时域电磁散射 ,并与试验作了对比 ,两者比较吻合

| Abstract: | A model called imposed excitation method for targets on the ground in time domain is described.The method comprises two steps:in the first step the scattering of the ground is calculated;in the second step the scattering of targets is calculated by imposing the scattering wave got at the first step upon the targets.A truck is involved in this paper.The scattering waves and RCS in VHF/UHF frequency are calculated.Good agreement between calculated and experimental results is obtained It shows the effectiveness of the method |
