| 摘 要： | 分析了在地面影响下的车体的散射.首先应用色散的时域有限差分 (FDTD)方法计算了车体与地面的时域波形,并得到了地面的反射系数,最后给出了车体的不同角度下的雷达散射截面(RCS)和成像结果,并与实验结果作了对比,两者十分吻合.

| Abstract: | A model for truck upon ground is described in time domain.The method takes two steps:the first calculates the scattering of ground,the second step calculates the scattering of targets by imposing the scattering wave got at first step upon the targets.A truck model is studied in this paper.The scattering waves and RCS in UHF band are calculated.Good agreements between calculated and experimental results are obtained.It shows the effectiveness of the method. |
