Abstract

This paper describes the experimental research efforts performed at the Swedish Defence Research Agency (FOI) concerning fundamental characterization of different wall and clothing materials as well as through-the-wall imaging. Results from on-going activities at FOI concerning material characterization in the millimeter wave range are presented. Wide-band measurements of five building materials have been carried out in two different ways. In the frequency range 0.04-40 GHz a vector network analyzer was used and the samples were positioned in waveguides. In the 2-120 GHz region a scalar network analyzer was used and transmission measurements of the materials were performed in free space. Transmission measurements in free space of two clothing materials were also performed. Results from measurements of a human target standing behind an inner wall are presented.
