The dielectric characteristics of trees are studied for a dielectric permittivity model of a forest stand of L1 band signals of navigation satellites. The contribution of the orientational ordering of tree elements and of the wood anisotropy to the effective wood dielectric permittivity ε has been estimated. The crown layer has the height-depend anisotropy ∆ε and the orientational ordering of branch tensor elements. The anisotropy gradients in the layer of trunks are determined by the height-dependent wood volume of a single tree and the tree height distribution in a large forest.

林分介电常数模型中树元素的方向排序

针对导航卫星L1波段信号林分介电常数模型，研究了树木的介电特性。已经估计了树木元素的方向排序和木材各向异性对有效木材介电常数 ε 的贡献。冠层具有高度相关的各向异性 ∆ε 和分支张量元素的取向排序。树干层中的各向异性梯度由单棵树的高度依赖的木材体积和大森林中的树高分布决定。
