Radar Tomography Using Maxwell's Equations

小行星9315787 研究所将开发一种新的雷达反演方法，从瞬态雷达数据中提取地下电导率和介电分布。 雷达实验几何结构将是表面源接收器配置和井间配置（即，一个井中的雷达源和相邻井中的电磁接收器）。 这种新方法的第一步，表示为麦克斯韦方程层析成像或MET是计算雷达电描记图的有限差分解决方案的完整的2-D或2.5-D麦克斯韦方程。 第二步是计算雷达图波形失配函数和初至走时失配函数。

9315787 Schuster The Pis will develop a new radar inversion method for extracting the sub-surface conductivity and dielectric distribution from transient radar data. The radar experimental geometries will be both the surface source receiver configuration and the crosswell configuration (i.e., radar sources in one well and electromagnetic receivers in an adjacent well). The first step of this new method, denoted as Maxwell Equation Tomography or MET is the computation of radar electrograms by finite-difference solution to the full 2-D or 2.5-D Maxwell's equations. The second step is to compute both a radargram waveform misfit function and a first arrival traveltime misfit function.
