Abstract

A new technique for measuring the effective dielectric constant of dense random media is presented. In this technique, the mean bistatic scattered fields of a cluster of random media, confined in a geometrical boundary, are measured using a monostatic radar and a rotatable ground plane and fitted to the bistatic scattered fields of a homogeneous lossy material with the same geometrical boundary. The accuracy of the bistatic measurement technique is verified by measuring the bistatic response of a number of canonical targets with known theoretical responses. The ability of the new technique in estimating the effective dielectric constant of a cluster of dense random media is demonstrated
