摘要

提出了一种半空间介质物体的重构方法。该方法基于逆散射公式。利用半空间的格林函数作为物体介电特性与散射电场样本之间的积分方程的核。通过构造求最小的泛函，将反问题转化为全局优化问题。采用微分演化方法求出该泛函的全局最小值。本文给出了该方法的数学公式。此外，还报道了数值结果。

Detection of buried objects by an electromagnetic method based on a differential evolution approach

A method for reconstructing dielectric objects buried in a half space is proposed. The approach is based on the inverse scattering formulation. The Green's function for the half space is used as the kernel of the integral equations relating the dielectric properties of the object to the samples of the scattered electric field. The inverse problem is recast as a global optimization problem by constructing a functional to be minimized. A differential evolution method is used to obtain a global minimum of this functional. The paper provides the mathematical formulation of the approach. Moreover, numerical results are reported.
