Abstract本文根据双曲型偏微分方程的特征线理论分析了分层媒质参数与时域反射信号的因果关系,了基于时域反射数据的分层媒质的参数反演的离攻化模型,结果表明,仅仅依靠电场域磁场的时域散射数据,不能实现分层有耗媒质介电常数和电导率的同时反演,数值模拟结果证明了分析的结论.
Other AbstractUsing the characteristic line theory of hyperbolic partial differential equations ,relations between the reflected signals and the dielectric parameters of the stratified media are analyzed.Studies about the discretized model of marching-on-in-time parameter inversion show the impossibility of simultaneous inversion of the permittivity and conductivity. Numerical simulation shows the validity of the theoretical analysis result.
