摘要

采用有限差分时域(FDTD)方法，通过施加表面阻抗边界条件(SIBC)来加速计算含水层上方超干旱土壤的散射场。提出了一种基于正入射后向散射场干涉图的地下水位深度估计方法。

Water-Table Detection in a Hyper-Arid Region

A finite-difference time-domain (FDTD) method, accelerated by imposing surface impedance boundary condition (SIBC), is implemented to compute the scattering fields from a hyper-arid soil above an aquifer. An estimation method of water-table depth beneath ground surface is proposed, which is based on the interference pattern of backscattering fields at normal incidence.
