摘要

本論文提出以線性取樣法與對比逆推法為基礎的遞迴演算法，以改善複數目標、層狀目標與連續漸變目標的還原的準確度，包括目標形狀、介電係數與導電率。本演算法經模擬結果證實，可克服尺寸或介電係數較大的目標在還原時所遭遇的部分困難，論文中亦呈現具有代表性的目標的改善成果。

A recursive approach, based on the linear sampling method (LSM) and the contrast source inversion (CSI) method, is proposed to improve the inversed shape and permittivity of
multiple targets, layered target and target with continuous profile. The difficulties of inversing targets with large electric size or permittivity are partly overcome using this approach, and the improvements are demonstrated using typical targets found in
the literatures.
