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.

Pis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。雷达实验几何形状将是地面源接收器配置和井间配置（即，雷达源在一口井中，电磁接收器在相邻井中）。这种新方法的第一步，称为麦克斯韦方程层析成像或MET，是通过对完整的2-D或2.5-D麦克斯韦方程的有限差分解计算雷达电图。第二步是计算雷达图波形失拟函数和初到旅行时间失拟函数。
