摘要
运用FDTD方法计算树干的宽带电磁散射特性。即将地面的散射场与入射场视为两个激励场作用于树干,从而得到地面背景下树干的散射场。给出了树干时域、频域、极化域和空域的电磁散射特性,并对这些特性进行了分析。
In this paper, the scattering characteristic of the tree is analyzed by using FDTD method. In order to deal with electromagnetic interaction of ground and tree, the incident field and the reflecting field of ground are treated as two excitated sources of the tree. The scattering fields of tree-teuck in frequency domain, time domain, polarization domain and space domain are simulated and discussed, respectively.
