Through-the-Wall Imaging by Stepped Frequency Radar Considering the Wall Effects

摘要

examination of effects of the wall in the imaging for the extended targets are important in through-the-wall imaging radar. High-resolution imaging through-the-wall can be implemented using a stepped frequency radar. The presented approach is suitable for simulating targets behind the wall with determined parameters. It is assumed that wall-parameters such as dielectric constant and thickness are known previously. In this article, we will evaluate defocusing and dispersion for targets located behind the wall.
