In through-the-wall target localization area, wall effect including absorption and refraction will arise, wall effect needs to be compensated. If wall parameters including thickness and dielectric constant are exactly known, the target can be compensated to its correct position. In this paper, based on the transmitting model of through-the-wall radar, we deduced the Cramer-Rao lower bound (CRLB) of...
Estimation of the basic parameters, wall thickness and dielectric constant, is important in through-the-wall radar imaging. Ambiguities in wall characteristics will degrade the image focusing quality of synthetic-aperture radar. In order to obtain a quick and precise estimation of wall parameters, an equivalent propagation model of an electromagnetic wave in the air–wall–air medium is first developed...
