Design and Evaluation of an Impulsive Ultrawideband System for Estimating the Moisture Content of Polyamide Targets

This article presents the design of an impulsive ultrawideband test bed, developed for remote sensing of dielectric targets. The platform is used for estimating the moisture content in polyamide targets. The main aspects of the design are presented, together with measurements of the constructed prototype. The capability of the platform to estimate the moisture content is explored and validated through measurements of Nylon 6 targets through a nonlinear regression algorithm. The experimental results show that the platform is capable of estimating the moisture content with good accuracy even when the target or the environment is not completely known.
