Abstract
In this paper ultra-wideband frequency modulated continuous-wave (FMCW) radar is used to investigate the properties of layered materials. The transceiver performs very accurate and fast measurements in the mm-wave region between 68 GHz and 92 GHz. Applying a Matching Pursuit Decomposition on the fast-time echo data, the reflection coefficients of the material sample are extracted. Using this information, the dielectric properties as well as the layer thickness can be evaluated. © 2018 IEICE
